1. Determination of Chopper Offset
for detailed test description see PTD_2.3.1 (->file attachment:chopper.pdf) or in CVS
- Chopper has to be switched-off and controller disabled
start PacketRecorder
start diag. HK with SPEC_Chopper_dhk_imt_OBS using Generic_CUS_script.tcl
- determine chopper offset (chop_offset) from DM_CHOP_CUR_POS
- include the new chopper offset in chopper control parameter set
-> PosOffset=(-1)*chop_offset
stop diag. HK with SPEC_Chopper_dhk_stop_OBS using Generic_CUS_script.tcl
close PacketRecorder
- switch-on chopper
- load up chopper control parameters including the new offset
-> tcl-script CONF_chopper_OBS.tcl with parameters fileU and calUcol
- enable chopper controller in order to upload new control parameter set
-> EnDis_chopper_OBS.tcl and parameter onoff ON
2. Chopper Open Loop Measurements
for detailed test description see PTD_2.3.1 (->file attachment:chopper.pdf) or in CVS
- chopper controller has to be enabled
start PacketRecorder
start script SPEC_Chopper_OpenLoop_MoveAbs_OBS.tcl given following parameters: chop_max_ma (maximum current in mA), chop_step_ma (current step width in mA) and chop_damptime (plateau duration in sec)
close PacketRecorder
- if neccessary disable and switch-off chopper
3. Verify function of Ge:Ga detectors, CREs and detector heaters PTD 0.7.3 (TBD!)
for detailed test description see PTD_0.7.3 (->file attachment:vergega.pdf) or in CVS
- prerequisites:
- PACS in spectroscopic mode
- blue detector heater should be around 2.1 K
- short test description:
- procedures consists of two tests, one in loss-less compression mode to get raw ramps and one in default mode
start with test in loss-less compression mode; detector selection table with 14 randomly selected pixel DXS7602 in both channels; execute CUS script SPEC_detector_fmilt073_detsel_llc_OBS.cus (called by tcl-script Generic_CUS_OBS.tcl); script lasts 1659 seconds
do then test in default mode; therefore, execute CUS script SPEC_detector_fmilt073_standard_OBS.cus (called by tcl-script Generic_CUS_OBS.tcl); script lasts 134
4. Chopper Synchronization PTD 0.7.6 (TBD!)
4.1. Spectroscopic Mode (TBD!)
for detailed test description see PTD_0.7.6_spec (->file attachment:chopsynspec.pdf) or in CVS
- prerequisites:
- PACS in spectroscopic mode
setup Chopper Configuration Parameter for 8 degree; use from CAL-U table CONFChopper the column FM_sa2_81deg
- short test description:
- we use the SPU mode loss less compression
detector selection table with 14 randomly selected pixel DXS7602 in both channels
use CUS script SPEC_Chopper_fmilt076spec_detsel_llc_OBS.cus for conducting this test (called by tcl-script Generic_CUS_OBS.tcl); script lasts 865 seconds
4.2. Photometeric Mode (TBD!)
for detailed test description see PTD_0.7.6_phot (->file attachment:chopsynphot.pdf) or in CVS
- prerequisites:
- PACS in photometric mode
setup Chopper Configuration Parameter for 8 degree; use from CAL-U table CONFChopper the column FM_sa2_81deg; to do this do following:
if chopper controller enabled, disable chopper controller with CUS script XXX (called by tcl-script XXX with parameters XXX)
do chopper configuration with CUS script XXX (called by tcl-script XXX with parameters XXX)
enable chopper controller with CUS script XXX (called by tcl-scritp XXX with parameters XXX)
- short test description:
- we use the SPU mode loss less compression
detector selection table with 14 randomly selected pixel DXS7602 in both channels
use CUS script PHOT_Chopper_fmilt076phot_detsel_llc_OBS.cus for conducting this test (called by tcl-script Generic_CUS_OBS.tcl); script lasts 51 seconds
5. Internal Calibration Sources PTD 0.7.11_12 & 2.5.3 (TBD!)
5.1. Functional and Performance Test
for detailed test description see PTD_0.7.11_12 (->file attachment:cs.pdf) or in CVS
- prerequisites:
- PACS in spectroscopic mode
- short test description:
- switch-on and enable CSs
- heat-up to CS1 and CS2 temperature value XX/XX (TBD) and stabilization at temperature plateau for in total 80 minutes
- go to a second temperature plateau (CS1=XX/CS2=XX;TBD) - 60 minutes
- cool-down (CS1=XX/CS2=XX;TBD) - script stops then 60 seconds after commanding the cool-down values; stop of recording file should be done after 60(TBD) minutes
use CUS script SPEC_CS_fmilt071112_swon_cs_perf_OBS.cus for conducting this test (called by tcl-script) Generic_CUS_OBS.tcl)
- CSs will not be switched-off
- comment:
- if necessary (e.g. in phase of control loop optimization) the temperature values in the CUS-script should be adapted
