PACS spectrometer operation from the commanding point of view

T. Mueller, D. Cesarsky; 10-Nov-2006

Index TableOfContents(2)

1. Short Functional Tests (Ge:Ga-detector related)

1.1. SFT Warm: Heater, flasher and Ge:Ga detector chain

PACS_Spec_OBS

1.2. SFT at HeI: Heater, flasher and Ge:Ga detector chain

PACS_Spec_OBS

1.3. SFT at HeII: Heater, flasher and Ge:Ga detector chain

PACS_Spec_OBS

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)
after execution: PACS is in SAFE mode

2.2. General Setup for Spectrometer Operation

starting out of SAFE mode
mode SPEC_setup_OBS calling the block SPEC_setup, calling the following CUS procedures:
- procedure SPEC_dpu_dmc_setup
- procedure SPEC_init_det_setup
- procedure SPEC_cre_selection
- procedure SPEC_gega_setup
- procedure SPEC_dmc_setup
  - procedure SPEC_fltw_conf
  - procedure SPEC_fltw_move
  - procedure CONF_chopper
  - procedure CHOP_on_off
  - procedure CONF_cs
  - procedure CS_on_off
  - procedure CS_temp
  - procedure CONF_grating
  - procedure GRAT_on_off
- procedure SPEC_spu_setup
ending up in Spectroscopy mode, but SPU processing has not yet started
filter is in position "A",
chopper enabled and at position "0"
grating is homed (with 1deg/sec) and enabled for nominal operations with a speed of 4deg/sec
calibration sources are set to default values, but need 40-50 min stabilisation time!!!

2.3. Operation of the spectrometers (starting out of '''Spectroscopy mode''')

2.3.1. start/stop of bolometer data flow

mode SPEC_spu_setup_OBS calling procedure SPEC_spu_setup ---> spectrometer data flow running
mode SPEC_spu_reset_OBS calling procedure SPEC_spu_reset ---> spectrometer data flow stopped

2.3.2. Take data with manual chopper, grating & filter movements

mode SPEC_spu_setup_OBS calling procedure SPEC_spu_setup ---> spectrometer data flow running
- mode PACS_fltw_move_OBS calling procedure SPEC_fltw_move (or PHOT_fltw_move)
- or command Pacs_DMC_MOVE_CHOP_ABS
- or command Pacs_DMC_MOVE_CHOP_REL
- or command Pacs_DMC_MOVE_GRAT_ABS
- or command Pacs_DMC_MOVE_GRAT_REL
mode SPEC_spu_reset_OBS calling procedure SPEC_spu_reset ---> spectrometer data flow stopped

Note: PACS_fltw_move_OBS can be called via a specific tcl-script where the filter has to be specified.

2.3.3. Take data with pre-defined OBCPs

mode OBCP_chop_scan_spec_OBS calling blocks/procedures:
- procedure SPEC_spu_setup
- procedure SPEC_fltw_move
- block OBCP_chop_scan_spec
- procedure SPEC_fltw_move
- block OBCP_chop_scan_spec
- procedure SPEC_fltw_move
- procedure SPEC_spu_reset
mode OBCP_grat_scan_nochop_OBS calling blocks/procedures:
- procedure SPEC_spu_setup
- block OBCP_grat_scan_nochop
- procedure SPEC_spu_reset
mode OBCP_spec_2_3_chop_OBS calling blocks/procedures:
- procedure SPEC_spu_setup
- block OBCP_spec_2_3_chop

- block OBCP_grat_line_scan_chop_2
- procedure SPEC_spu_reset
mode OBCP_gra_scan_chop2_fast_OBS calling blocks/procedures:
- procedure SPEC_spu_setup
- block OBCP_gra_scan_chop2_fast
- procedure SPEC_spu_reset
mode OBCP_spec_freq_switch_OBS calling blocks/procedures:
- procedure SPEC_spu_setup
- block OBCP_spec_freq_switch
- procedure SPEC_spu_reset
mode OBCP_chop_grat_scan_cal_OBS calling blocks/procedures:
- procedure SPEC_spu_setup
- block OBCP_chop_grat_scan_cal
- procedure SPEC_spu_reset
mode SPEC_all_aots_OBS calling the following blocks/procedures:
- procedure SPEC_spu_setup
- procedure SPEC_fltw_move
- block OBCP_spec_2_3_chop
- block OBCP_spec_2_3_chop_dither
- block OBCP_grat_line_scan_chop_2
- block OBCP_grat_scan_chop2_fast
- block OBCP_grat_scan_nochop
- block OBCP_spec_2_3_chop
- block OBCP_chop_grat_scan_cal
- block OBCP_chop_scan_spec
- block OBCP_spec_freq_switch
- procedure SPEC_fltw_move
- block OBCP_spec_2_3_chop
- block OBCP_spec_2_3_chop_dither
- block OBCP_grat_line_scan_chop_2
- block OBCP_grat_scan_chop2_fast
- block OBCP_grat_scan_nochop
- block OBCP_spec_2_3_chop
- block OBCP_chop_grat_scan_cal
- block OBCP_chop_scan_spec
- block OBCP_spec_freq_switch
- procedure SPEC_fltw_move
- procedure SPEC_spu_reset

Note: all these modes can be started with default parameters via the generic tcl-script; the key-OBCPs can also be started with freely selectable parameters via specific tcl-scripts

2.3.4. Execute AOT observations

CUS scripts (to be finalised):BR

2.4. Reset after spectrometer operation

PACS is in SPECTROSCOPY
execute mode SAFE mode

2.5. Instrument switch-off

currently done with the tcl-script PACS_Switch_Off.tcl (maintained by FGB)
after execution: PACS is switched off

3. Specific Spectrometer Tests

3.1. Thermal Behaviour Test

starting out of SAFE mode
mode SPEC_thermal_OBS calling the following blocks/procedures:
- procedure SPEC_dpu_dmc_setup
- procedure CONF_chopper
- procedure CHOP_on_off
- block OBCP_spec_2_3_chop
- procedure CONF_grating
- procedure GRAT_on_off
- block OBCP_spec_2_3_chop
- block OBCP_spec_2_3_chop
- procedure SPEC_fltw_conf
- procedure SPEC_fltw_move
- procedure CONF_cs
- procedure CS_on_off
- procedure CS_temp
- procedure SPEC_dpu_dmc_reset
ending up in SAFE mode

3.2. SPU Modes & Detector Selection Tests

3.3. Other Tests

4. NOTES

the SFT tests are described in PACS-ME-TP-007
some specific spectrometer tests, like the thermal behaviour measurement, start directly out of SAFE mode, while most of the tests will be executed after the SPEC_setup_OBS when the instrument is in Spectroscoy mode
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
