Start the new users at the beamline¶
newmac
(# uploading all the macros )userslist.mac
cd Scripts/
./newusers-4b.sh 2022-3 sarker-0000-a
( this will create file both in id4b and id4baux )- copy HRDMscans.mac to the specific folder
- FOURC >
qdo ./HRDMscans.mac
- FOURC >
newfile (name of newfile)
- Change the HDRMscans.mac file with
_samplename
and_sampledirectory
Open the camera inside the front hutch¶
- Open an terminal
- type
vimba
- Vimba viewer will open with two cameras ( IP addresses: 1st crystal:
192.168.180.102
, 2nd crystal :192.168.180.101
)
Open ion chambers¶
- Open an terminal
- type
show_apms 0
- type
show_apms 1
- type
show_apms 2
for FOURC opening¶
- Open an terminal
- type
fourc
- press
yes
if fourc ask questions to change motor values
STEP 1: If you lost fourc/SPEC terminal¶
- Open terminal
- type
findspec
(it will provide all the spec information) - Check the getPid number
- type
fg <getPid number>
(example # fg 21192)
STEP 2: Talk to beamline scientist¶
If you doesn't find anythng after STEP 1 fourc/SPEC terminal
* If you not find the SPEC terminal, then type below command
* kill -9 <getPid number>
(example# kill -9 21192)
* Open a new terminal
* Type ‘fourc’
If you fourc/SPEC doesn't work¶
- Open terminal
- type
quit
- type
fourc
If SPEC window is lost¶
- Open an terminal
- type
findspec
- If it is hidding, then type
fg <PID number>

Step I:
* Cover the detector
* Before energy change (> 30 keV higher to lower < 18 keV)
verify counts in ic1, ic2 and diode (getE

Put mostab to 5 V
Optimize counts (tweakup

Setup :
mv pil6mx 100 mv pil6my 760
mv pil6mx 100
- move pilatus 6M to 100 mm x directionmv pil6my 760
- move pilatus 6M to 760 mm y direction
To take the detecotor all the way end of the hutch
