## Attenuation
|
|
This device has 3 Kapton layers:
|
|
- 50 um kapton [Drawing](http://planarchiv.psi.ch/plandb_pub/p_plandb_cus_pub_sucw.viewItem?pId=197918&pPosInQueryList=1&pCount=831&pIndexInQueryList=68&pKrz=&pHg=50024&pUg=24&pLnr=&pAnlage=&pBaugruppe=&pBenennung=&pFremdNr=&pGueltig=GUL)
|
|
- 125 um kapton
|
|
- approx 20 um black kapton
|
|
|
|
## Device motion
|
|
The following motors are used to scan the device position, used for calibration of the device
|
|
- SARFE10-PBPS053:MOTOR_X1 (range -1.8, 2.5 mm)
|
|
- SARFE10-PBPS053:MOTOR_Y1 (range -2.3 , 1.7 mm)
|
|
Values:
|
|
- SARFE10-PBPS053:MOTOR_X1.VAL
|
|
- SARFE10-PBPS053:MOTOR_Y1.VAL
|
|
|
|
## Modification history
|
|
- 02.11.20 Replaced 50 um kapton with approx 20 um black kapton, exchanged 50 nm Si3N4 with new target as old target looked burnt (brown beam profile on target)
|
|
- 07.01.21 Added 125 um and 50 um kapton in front of diodes as attenuation
|
|
- 21.12.22 Replaced lower 50 um Si3N4 and 30 un Si3N4 targets with burn marks
|
|
