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

  • mode BOLO_cooler_OBS calling the CUS procedure BOLO_cool_recycle:BR

    • - no sub-procedures are called, the groups and temperature sensors are not touchedBR - HK_list is set to PHOT_HK and reset to "NON-PRIME" in the endBR - 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: --> HK DEC SOFT is generated if one or more are out of the range [260,320] mK; --> GO SAFE is generated if one or more are above 400 mK

2.3. General Setup for Photometer Operation (after cooler recycling)

  • starting out of SAFE mode (groups off, temperature sensors on)BR

  • mode PHOT_setup calling the following CUS procedures:BR

    • - procedure PHOT_dpu_dmc_setupBR - procedure PHOT_dmc_setupBR

      • - procedure PHOT_fltw_conf BR - procedure CONF_chopper BR - procedure CONF_cs BR

      - procedure PHOT_switchon_groupsBR - procedure PHOT_set_bias (*)BR - procedure PHOT_seq_setupBR - procedure PHOT_change_data_modeBR - procedure PHOT_change_seq_modeBR - procedure PHOT_set_gain(**)BR - procedure PHOT_spu_setupBR

  • ending up in PHOTOMETRY mode, but SPU processing has not yet startedBR

  • 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)

2.4.2. Change of the bolometer data/sequence mode and gain

  • - procedure PHOT_change_data_modeBR - procedure PHOT_change_seq_modeBR - procedure PHOT_set_gainBR - or via MSTK with individual commands

2.4.3. Take data with manual chopper & filter movements

    mode PHOT_spu_setup_OBS calling procedure PHOT_spu_setup ---> bolometer data flow running BR

    • - mode PHOT_all_aots_OBS calling the following procedures:BR

      • - procedure OBCP_chopped_photometryBR - procedure OBCP_chopped_photometry_ditherBR - procedure OBCP_phot_freezeframeBR - procedure OBCP_phot_cal_IBR - procedure OBCP_phot_cal_IIBR - procedure OBCP_phot_cal_IIIBR - procedure OBCP_phot_staringBR - procedure OBCP_phot_chopper_scanBR - procedure OBCP_fixed_fixed_photoBR

        - PHOT_aot_epilogueBR - WriteEndIDBR - PacsPhotNoiseRMSBR - PacsMessageCenterBR

Note: the default OBCP for point-source photometry will probably be the OBCP_fixed_fixed_photo.

2.5. Reset after photometer operation

  • PACS is in PHOTOMETRY or any other mode

  • execute mode PHOT_switchoff_groups_OBS calling procedure PHOT_switchoff_groups (this will reset the biases sequentially, disable the AF 17, and switch off the groups)

  • going into SAFE mode (this will disable the AF 14 for the FPU temperature checks)
  • after execution: PACS is in SAFE mode (groups are off, temperature sensors on, AF 6 enabled to check for the communication between DMC and BOLC)

2.6. Instrument switch-off

  • currently done with the tcl-script PACS_Switch_Off.tcl (maintained by FGB) (this will disable the AF 6 for the DMC-BOLC communication check)

  • after execution: PACS is switched off

3. NOTES

  • the SFT tests are described in PACS-ME-TP-007

  • 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 library
  • the AOT related CUS-scripts are still under testing
