2. Nominal operations
2.1. Instrument switch-on and connection of the warm electronic boxes
- currently done with tcl-script PACS_Switch_On.tcl (maintained by FGB)BR - after execution: PACS is in SAFE mode, the bolometer groups are off, but the temperature sensors are onBR
Note: Autonomy function #6 is enabled to check for the communication between DMC and BOLC
2.2. Cooler recycling (only at HeII temperatures)
- starting out of SAFE mode (groups off, temperature sensors on) BR - CUS script:BR
mode BOLO_cooler_OBS calling the following CUS procedure:BR
- procedure BOLO_cool_recycle (no sub-procedures are called, the groups and temperature sensors are not touched, HK_list is set to PHOT_HK and reset to "NON-PRIME" in the end, autonomy function 14 is enabled), Duration: 7928 secBR
- ending up in SAFE mode (groups are off, temperature sensors on, HSP heater current at 1.18 mA)BR
Note: At the end of the recycling the autonomy function 14 is enabled. It checks for TEMP_EV, TEMP_FPU1, TEMP_FPU2:BR
--> HK DEC SOFT is generated if one or more are out of the range [260,320] mKBR --> GO SAFE is generated if one or more are above 400 mKBR
2.3. General Setup for Photometer Operation (after cooler recycling)
- starting out of SAFE mode (groups off, temperature sensors on)BR - CUS script:BR
block PHOT_setup calling the following CUS procedures:BR
(*) the bias tables to be loaded might change!BR
- ending up in PHOTOMETRY mode, but SPU processing has not yet startedBR - Note: filter is in position "A", chopper at position "0"BR - calibration sources are set to default values, but need 40-50 min stabilisation time!!!BR
Note: At the end of the PHOT_setup the autonomy function 17 "generate_event_pwr" is enabled. It checks for the HK entries: PC_PWR_ANA_P_#, PC_PWR_ANA_N_# and PC_PWR_DIG_#, with # = [1,2,3,4,5,6,7]
2.4. Operation of the bolometers (starting out of PHOTOMETRY mode)
2.4.1. start/stop of bolometer data flow
CUS scripts:BR
2.4.2. Change of the bolometer data/sequence mode and gain
CUS scripts:BR
2.4.3. Take data with manual chopper & filter movements
CUS scripts:BR
2.4.4. Take data with pre-defined OBCPs
CUS scripts:BR
- procedure PHOT_spu_setup ---> bolometer data flow runningBR
- block OBCP_chopped_photometryBR - block OBCP_chopped_photometry_ditherBR - block OBCP_phot_freezeframeBR - block OBCP_phot_cal_IBR - block OBCP_phot_cal_IIBR - block OBCP_phot_cal_IIIBR - block OBCP_phot_staringBR - block OBCP_phot_chopper_scanBR
- block PHOT_all_aots_OBSBR
- procedure PHOT_spu_resetBR
2.4.5. Execute AOT observations
CUS scripts (to be finalised):BR
PHOT_AOTBR
- PacsPhotDefaultsBR - PacsPhotEstimatorOBCPnBR
Logic chooses and issues a pointing mode out of:BR
- WriteOBSIDBR - PacsPhotSlewCalBR
- PacsPhotCommandOBCP7BR
- OBCP_staring_photometryBR
- PacsPhotCommandOBCP5BR
- OBCP_chopped_photometry_ditherBR
- PHOT_aot_epilogueBR - WriteEndIDBR - PacsPhotNoiseRMSBR - PacsMessageCenterBR
2.5. Reset after photometer operation
- PACS is in PHOTOMETRY or any other modeBR - going into SAFE mode:BR
- after execution: PACS is in SAFE modeBR
2.6. Instrument switch-off
- currently done with the tcl-script PACS_Switch_Off.tcl (maintained by FGB)BR - after execution: PACS is switched offBR
3. NOTES
- the SFT tests are described in PACS-ME-TP-007BR - some specific photometer tests, like the thermal behaviour measurements, start directly out of SAFE mode, while most of the tests will be executed after the PHOT_setup - the above mentioned CUS scripts (with a few exceptions) have been tested and are available in the CUS database and from the CVS libraryBR - the AOT related CUS-scripts are still under testing
