Contact Information ------------------------------------------------------------------------------- If you have any questions regarding this file contact SPICE support at ESAC: Alfredo Escalante Lopez (+34) 91-8131-429 spice@sciops.esa.int or the JUICE Science Operations Center at ESAC: Marc Costa Sitja (+34) 646-746-711 Marc.Costa@ext.esa.int Implementation Notes ------------------------------------------------------------------------------- Applications that need SPICE I-kernel data must ``load'' the I-kernel file, normally during program initialization. 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 furnsh( frame_kernel_name ) -- PYTHON* 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 and cspice.getfov in PYTHON) 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, cspice.gcpool in PYTHON). See [2] for details. This file was created with, and can be updated with a text editor or word processor. * SPICEYPY is a non-official, community developed Python wrapper for the NAIF SPICE toolkit. Its development is managed on Github. It is available at: https://github.com/AndrewAnnex/SpiceyPy 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 one of the RADEM sensors. This is the full list of names and IDs for the RADEM sensors described by this IK file: Name NAIF ID --------------------- --------- JUICE_RADEM_ESD -28086 JUICE_RADEM_PSD -28087 JUICE_RADEM_HISD -28088 JUICE_RADEM_DD_NN* -28089NN* JUICE_RADEM_BKGD_N** -28089NN* * NN is the sector number and ranges from 00 to 27. ** N is the background sector and ranges from 1 to 3. The remainder of the keyword name is an underscore character followed by the unique name of the data item. For example, the RADEM Electron Stack Detector boresight direction in the JUICE_RADEM frame is specified by: INS-28921_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 ------------------------------------------------------------------------------- From [5]: The RADEM instrument will serve as an on–board radiation monitor providing information on particle fluxes and their energy spectra. RADEM consists of three separate detector sub–units: - Electron Detector Head - Proton & Heavy Ion Detector Head - Directional Detector Head Each of them is connected to a readout Application–Specific Integrated Circuit (ASIC) designed especially for the JUICE mission. It is designed to measure electrons from the 0.3-40 MeV energy range, 5-250 MeV protons, and heavy ions up to the Oxygen within the Linear Energy Transfer range from 0.1 to 10 MeV cm mg−1. The main scientific goals for RADEM are: - Characterization of Jupiter's harsh radiation environment - Study of dynamics in Jovian radiation belts - Understanding of trapped particle energy gain and loss - Space weather monitoring across the Solar System - Comparison between Jupiter and Earth radiation environment The design of the RADEM detector sub–units makes the sensors almost directly exposed to the radiation through the openings of the entrance collimators. Consequently, all the sensors used in the instrument had to be able to withstand the maximum predicted radiation dose while maintaining their original spectroscopic functionalities virtually unchanged. All sensitive electronic components used in RADEM are radiation–hard up to 100 krad which indicated the need for the application of even 14 mm Al thickness equivalent shielding. To keep up with the volume limit, the RADEM shielding contains local tantalum plates to reduce the dose at the most sensitive components. The final mass of the instrument after application of all necessary components stays under 5 kg. Because of the telescope structure of electron and proton detector sub-units, RADEM is capable of discriminating between them, on–line discarding the unwanted particle type. In addition to its spectroscopic functions, RADEM will continuously provide the radiation dose values deposited by each particle species. Dose values will be given for different shielding depths and updated every 10 seconds. RADEM is designed for the operation that allows for in-flight remote calibrations and reconfiguration of the detector logic and analog parameters, allowing for adjustment during the mission time. Each of the three RADEM detector heads is a separate sub–unit, dedicated to a specific task and working independently on each other. It consists of a set of silicon sensors and absorbers surrounded by a copper collimator. Detector heads have their corresponding front–end electronics that includes the dedicated ASIC and all the necessary wiring. All the diodes used in RADEM models are 300μm thick, n–doped silicon sensors. The Electron Detector Head (EDH) is the most crucial, from the mission safety point of view, sub–unit of RADEM. It is designed to provide information on electron energy spectra between 0.3 and 40 MeV. Si–diode sensors of the detector head are organized in the stack structure. Diodes are mounted under the collimator entrance window, one on top of another, separated by absorbers and spacers. This structure is named the Electron Stack Detector (ESD). The opening angle of the copper collimator equals 15 degrees which corresponds to the coverage of nearly 0.5% of the sky. The 0.4 mm thick Al entrance window is located after the collimator entry, before the first diode, to cut off lower–energy electrons, protons and heavy ions, and define the low energy threshold of the telescope. Detector stack contains eight Si diodes, first one of the 3 mm, others of 6 mm diameter. Diodes are separated by four Al and three Ta absorbers. It assures the full coverage of the electron detection spectrum by 8 energy bins, equally distributed on the logarithmic scale. The Proton and Heavy Ion Detector Head (P&HIDH), contains two separate detector stacks: Proton Stack Detector (PSD) and Heavy Ion Stack Detector (HISD), connected to one ASIC and shielded by the common collimator with two separated circular opening for both detector stacks. The detector head is designed to measure protons of the energy between 5 and 250 MeV. The heavy ion part is optimised for the detection of ions between Helium and Oxygen in the energy range from 8 to almost 700 MeV. The geometry and working principles of PSD are very similar to ESD. As the anticipated proton flux is by almost one order of magnitude lower comparing to the electron one, the opening angle of the collimator was widened to 20 degrees. It led to an increase in the coverage of the sky to almost 0.8%. The Aluminum entry window with a thickness of 0.2 mm defines the low energy thresholds for proton detection. HISD contains only two, 12 mm diameter diodes, located under the 20 mm high copper collimator. This design results in the coverage of the sky on a level of 15%. No absorbers are used in HISD and its entry window serves the role of mechanical damage prevention as its thickness is only 0.1 mm. The Directional Detector Head (DDH) consists of a single, pixelated Si disk with 31 sensitive areas covered with copper shielding containing 28 apertures. Its lower part is covered by a 0.5 mm thick entry window made of Kapton. Openings of the collimator point towards four zenithal directions: 1x0 degrees, 9x22.5 degrees, 9x45 degrees and 9x67.5 degrees, and also cover nine azimuth directions spaced by 40 degrees over the full 360 degrees angle. Each aperture leads to one dedicated pixel of the diode which size and shape fit the projection of the collimator entry hole onto the diode plane. Openings of the collimator entries have the diameter of 1 mm and their length equals 8 mm, corresponding to the opening angle of around 7 degrees. The DDH has three extra sensors (adding up to 31) are the sensors that do not have collimator apertures above them and are used to veto background ging through the collimator 8 mm of Copper with an effective FOV of 2 Pi srs (from [6]).
