User manual of 7-element SDD by SPEC (BL14B2)

9.27.2023 Hironori Ofuchi

1. Preparation before using 7-element SDD(1) Set the 7-element SDD on the X-Z stage.

(2) Connect the power cable (SPEC PC, DSPs, and hub) to power tap.

(3) Connect the DSP and fan cable to the 7-element SDD.

(4) Connect the signal cables to the 7-element SDD. Each connecter number (DEC1-7) is labeledon each signal cable.

(4) Connect LAN cable to the hub.

(5) Turn on the 7-element SDD PC.

(6) Turn on the power supply of DSPs.

(7) Log in the 7-element SDD PC and run “DSP MCA” program on desktop (by staff). Exit theprogram after confirming that the program has started.

(8) Start software “Teraterm” to login SPEC server (192.168.71.2). Login SPEC server (by staff).

(9) Run “xafs –l speclog/xafs_********.tlog” (******: date).

2. Setting of 7-elements SDD(1) Run “HV_on_sdd” macro.

0000.XAFS> HV_on_sdd(2) Run “sdd_on” macro.
0000.XAFS>SDD_off

0000.XAFS> sdd_on(3) Run “setdir_7sdd” macro to set data storage directory.
setdir_7sdd dir
0000.XAFS>

HV_off_sdd

0000.XAFS> setdir_7sdd 20220101(4) Set standard sample in sample holder.
(5) Run “set_all_db_roi” macro to read ROI parameters from the database.
setdir_7sdd element-edge
0000.XAFS> set_all_db_roi Cu-K
If the ROI parameters are not registered in the database, the message ”指定したフォルダは存在しない” will be displayed.
(5) Open DSS. Run “ct ; get_all_count” macro to count intensity of SDD.
0000.XAFS> ct ; get_all_count(6) Run “sdd_mca_out” macro to save mca data file. The Mca data file is saved in/xafsuser/xas/mca directory at SPEC server.
0000.XAFS> sdd_mca_out CuO_mca(7) Open mca data by Excel, and check ROI.

(6) Run “put_roi_all” macro to set ROI parameter.
put_roi_all min max
0000.XAFS> put_roi_all 350 520(8) Run “put_roi” macro when you want to change ROI parameter for specific channel.
put_roi min max channel_number
0000.XAFS> put_roi 300 450 5

3. Measuring deadtime correction data (if needed)(1) Set the attenuator downstream of the second mirror.
(2) Adjust value of ssdx so that ICR counts of SDD become 250,000 – 300,000 cps atmaximum.
(3) Run “kazoe_sdd” macro.
kazoe_sdd att dewll_time filename
0000.XAFS> kazoe_sdd att 10 deadtime_10s_Cu_K_A_mode_20220101

4. Measuring XAFS spectrum(1) Set sample in the sample holder.

(2) Run “DSS_op” macro to open DSS shutter.
0000.XAFS> DSS_op(3) Run “ct; get_all_count” macro to count intensity of SDD.
ct ; get_all_count0000.XAFS> ct; get_all_count
ICR_CH1 = 11931 count , SCA_CH1 = 9855 count,

ICT_CH1 = 12154 count

ICR_CH2 = 11824 count , SCA_CH2 = 9729 count,

ICT_CH2 = 11965 count

ICR_CH3 = 11988 count , SCA_CH3 = 9858 count,

ICT_CH3 = 12166 count

ICR_CH4 = 11924 count , SCA_CH4 = 9899 count,

ICT_CH4 = 12047 count

ICR_CH5 = 11553 count , SCA_CH5 = 9490 count,

ICT_CH5 = 11660 count

ICR_CH6 = 11949 count , SCA_CH6 = 9907 count,

ICT_CH6 = 12076 count

ICR_CH7 = 11696 count , SCA_CH7 = 9663 count,ICT_CH7 = 11775 count(4) Adjust value of ssdx so that ICR counts of SDD become 250,000 cps at maximum.
0000.XAFS> mv ssdx 50(5) Run “getparam” macro to set parameter of step-scan XAFS.
getparam dir/filename
0000.XAFS> getparam /home/xafsuser/xas/par/Cu-K_111_k16_1s.pard value = 3.135510

(6) Run “xas_scan” macro to start measuring step-scan XAFS.
xas_scan filename SDD repetition_number
0000.XAFS> xas_scan CuO SDD 1

5. Suspending measurement(1) Push “Ctrl-C” key to stop measurement.
(2) Run “recover_mono_all” macro to recover Y1 axis of monochromator.
0000.XAFS> recover_mono_all(3) Run “close_opned_files” macro.
0000.XAFS> close_opned_files

6. After measurement(1) Run “sdd_off” macro.
0000.XAFS>SDD_off

0000.XAFS> sdd_off(2) Run “HV_off_sdd” macro to stop HV of SDD.
0000.XAFS>

HV_off_sdd

0000.XAFS> HV_off_sdd(3) Turn off power supply of DSPs.
(4) Turn of the SDD PC.
(5) Disconnect LAN cable to hub.
(6) Disconnect signal cables to SDD.
(7) Disconnect DSP and fan cable to SDD.
(8) Disconnect powder cable (SPEC PC, DSPs, and hub) to power tap.
(9) Remove 7-element SDD on X-Z stage.
