The SPICE routine FURNSH loads a kernel file into the pool as shown below. CALL FURNSH ( 'frame_kernel_name' ) -- FORTRAN furnsh_c ( "frame_kernel_name" ); -- C cspice_furnsh, frame_kernel_name -- IDL cspice_furnsh( 'frame_kernel_name' ) -- MATLAB Loading the kernel using the SPICELIB routine FURNSH causes the data items and their associated values present in the kernel to become associated with a data structure called the ``kernel pool''. Once the file has been loaded, the SPICE routine GETFOV (getfov_c in C, cspice_getfov in IDL and MATLAB) can be used to retrieve FOV parameters for a given instrument or structure. The application program may obtain the value(s) for any other IK data item using the SPICELIB routines GDPOOL, GIPOOL, GCPOOL (gdpool_c, gipool_c, gcpool_c in C, cspice_gdpool, cspice_gipool, cspice_gcpool in IDL and MATLAB). See [1] for details. This file was created with, and can be updated with a text editor or word processor. Naming Conventions and Conventions for Specifying Data ------------------------------------------------------------------------------- All names referencing values in this IK file start with the characters `INS' followed by the NAIF JUICE spacecraft ID number (-28) followed by a NAIF three digit ID code for the PEP sensors. This is the full list of names and IDs for the PEP instrument described by this IK file: Name NAIF ID --------------------- --------- JUICE_PEP_JDC -28510 JUICE_PEP_JNA -28520 JUICE_PEP_NIM -28530 JUICE_PEP_JEI -28540 JUICE_PEP_JOEE -28550 JUICE_PEP_JENI -28560 The remainder of the keyword name is an underscore character followed by the unique name of the data item. For example, the NIM boresight direction in the JUICE_PEP_NIM frame is specified by: INS-28530_BORESIGHT The upper bound on the length of the name of any data item is 32 characters. If the same item is included in more than one file, or if the same item appears more than once within a single file, the latest value supersedes any earlier values. Instrument Description and Overview ------------------------------------------------------------------------------- PEP consists of four major hardware units which are distributed in two main groups (see [6]). The PEP instrument structure is shown in the simplified product tree below: JUICE Mission System Level | - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - | Element Level ,------------------+------------------------------. | | | PEP Other Instruments Spacecraft | - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - |-------------------------------------------------. Group Level | | PEP-Lo PEP-Hi | | - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - |---------------------. .----------------| Unit Level | | | | Nadir Unit (NU) JDC JoEE JENI | | | | - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - |---------------. | | | Sensor Level | | | | | | NIM JEI JNA JDC JoEE JENI - Nadir Unit (NU), which carries three sensors (NIM, JEI, JNA) and the related electronics accommodated in the card rack (CR). The CR contains the common power converters (DCC) and data processing unit (DPU), as well. The DPU is redundant. The Baseplate (BP) is the mechanical structure which supports the five sensors and the CR, whereby the latter is bolted to the bottom side and is therefore buried below the S/C panel for optimized radiation protection. The NU has direct electrical I/F to the S/C and is electrically connected to JDC. - The Jovian plasma Dynamics and Composition analyzer Unit (JDC) is a reflectron type time-of-flight (TOF) ion mass spectrometer with full hemisphere coverage. The sensor consists of a elevation steering unit, an electrostatic analyser, a time-of-flight (TOF) section using particle – surface interaction to generate start and stop signals, and a reflectron. The TOF section uses channel electron multipliers to generate start pulses and an MCP for stop pulses. The section is also equipped with an anti-coincidence solid state detector. Both start and stop detectors are strongly shielded with WCu alloy to reduce noise generated by penetrating energetic radiation. By switching HV polarity JDC is capable of measuring both positive and negative ions and electrons. - JENI is a combined energetic ion sensor and energetic neutral atom (ENA) camera. The sensor consists of a set of large, thin serrated magnesium plates that deflect charged particles via an applied 8kV electric field. Neutral atoms which pass completely through the plates pass through a pair of very thin (1 micro-grams/cm2) foils and strike a large MCP (~44cm2). Secondary electrons from the two foils are steered to a second large MCP (~48cm2). Both MCP sets are mated with position-sensitive anodes and housed in machined Ultem housings. The neutral atoms can instead strike one of eight 100 microns thick solid state detectors. The deflection plate assembly, detector elements, and electrostatic steering wires are mechanically supported by a magnesium structure that is heavily shielded by tungsten copper plates to provide radiation shielding. To optimize radiation protection efficiency the electronics is arranged below the interface plane to the S/C panel. JENI has electrical interfaces to the S/C, and JoEE is electrically connected to JENI. - JoEE is a compact medium-high energy electron spectrometer, in which electrons are deflected onto a set of pie-shaped solid state detectors via 16 radially aligned permanent magnets configured in a self- closing field. The sensor elements are housed in an aluminium structure that is heavily shielded by tungsten copper material to provide radiation shielding, and is based on the successful Galileo/ LEMMS and Cassini/LEMMS sensors and the newer Juno/JEDI electronics. These three hardware units host a set of six sensors that comprise the complete PEP instrument: - The Neutral gas and Ion Mass spectrometer (NIM), which is a time-of-flight (TOF) type mass spectrometer. The sensor consists of a titanium tube, which carries ion source (IS) and detector (DET) on one side and integrated reflectron (IR) on the other. IR and IS are metal-ceramic components joined by vacuum brazing and electron beam or laser welding. The DET consists of a micro channel plate (MCP) with diameter of 10 mm and is heavily shielded with Tantalum and Aluminum to suppress the noise caused by the Jovian radiation environment. The sensor is mounted to the NU baseplate via a tubular structure. Two hoods are foreseen to mechanically protect the ion optical components and at the same time prevent direct exposure of high voltages. - The Jovian Electrons and Ions (JEI) analyzer, which measures the thermal and hot electron and ion distributions without mass resolution in all regions traversed by JUICE. JEI covers the energy range from 1eV to 20 keV with full hemispheric coverage and 20 kev and 50 keV with a limited field-of-view. Sweeping voltage across the entrance deflector system allows determination of the particle arrival direction. The deflector is followed by a spherical electrostatic analyzer to determine the particle energy. Switching between the electron and ion mode is achieved by switching of the positive voltages from inner to outer ESA sphere. All deflectors use only positive voltages to simplify the high voltage power supply. To further reduce the background count rate due to penetrating radiation an anti-coincidence solid state detector (SSD) below the CCEM plane is introduced. The SSD is of annular shape with three 120-degree sectors covering the entrance cones of the respective CEM blocks. - The Jovian Neutrals Analyzer (JNA), which a surface interaction energetic neutral atom (ENA) instrument. The sensor consists of a half-disk shaped entrance system protruding through the baseplate and a combined detector and electronics box below the baseplate. Incident ENAs are ionized on a conversion surface, energy analyzed and post accelerated to the time-of- flight (TOF) section located in the detector and electronics box. Start and stop signal for the TOF measurements are both provided by microchannel plates (MCP). An equivalent of 20mm of Al shielding consisting of a layering of Al/Pb/Ta/Al is used to protect the MCP from penetrating energetic radiation in the Jovian environment. The instrument has all electronics integrated in its own electronics box and interfaces only with power and telemetry to the common electronics rack. Mounting Alignment ------------------------------------------------------------------------------- Refer to the latest version of the JUICE Frames Definition Kernel (FK) [3] for the PEP reference frame definitions and mounting alignment information. Sensors Sector Layout ------------------------------------------------------------------------------- This section contains assignments specifying the sensors layout by defining individual sector view directions for each of the PEP sensors. The combined aperture of each of the sensors is broken down into a number of equally spaced sectors to achieve the necessary spatial resolution within the sensor's sensor plane and in the direction normal to it. This table summarizes the individual sensor sector layout (based on [5]): --------- --------------------- --------------------- Sensor Number of Sectors Sector size, deg Name in-plane cross-plane in-plane cross-plane --------- -------- ----------- ---------- ----------- JDC 18 16 19.5 5.5 JNA 2 6 7.0 150.0 NIM 4(1) 1 90.0 10.0 JEI 36 4 10.0 20.0 JOEE 1 8 12.0 22.0 JENI 45 60 2.0 2.0 --------- --------------------- --------------------- (1) Currently, there's no information about sectorial division of the NIM sensor. The toroidal FoV of 360x10degrees have been split in four quadrants in order to support its description. The parameters from the table are provided for each sensor using the following keywords: NUMBER_OF_SECTORS -- contains two integers for in-plane and cross-plane sector numbers SECTOR_SIZE -- contains only two numbers for in-plane and cross-plane sector size in degrees FRAME -- contains the name of the frame in which the sector view directions are defined SECTOR_DIRECTIONS -- contains sector center view directions for each sector in the sensor symmetry plane. The order of vectors in the SECTOR_DIRECTIONS is different for different sensors. It is described for each particular sensor in that sensor's section of this IK. JDC sensor layout and Field-of-View definitions ------------------------------------------------------------------------------- This section contains the Jovian plasma Dynamics and Composition (JDC) analyzer sensor layout and field-of-view (FoV) definitions. The JDC full field of view is 360x90degrees, split in 288 sectors -- 18 in-plane (azimuthal) by 16 cross-plane cross-plane (polar) direction. In the in-plane direction the sectors are numbered from 0 to 17, in the cross-plane direction the sectors are numbered 0 to 15. All of the in-plane sectors are 19.5 degrees wide with their center view directions 20.0 degrees apart. In the cross-plane direction all sectors have the same size of 5.5 degrees with their center view directions ~5.52424 degrees apart.
