How to rotate the HWP on the REFL table

How to roate the REFL HWP for the REFL power change

Please see June Gyu's post for the HWP position on the REFL table.

ssh 10.68.10.250
cd Desktop/
sudo python agilis_control.py 1 1 1000

Note that this is a temporary solution.
IMC REFL HWP rotator is offline tonight

Technical details:

[Oshino, YamaT, Kokeyama]

The usual scheme with k1ctr8 did not work with an unknown error. Oshino-san suggested to remove the first USB (for IMC REFL) and rebooted the workstation, but it didn't work. Also, the commertial app on a windows machine did not work. Probably windows (running on the DGS macbook) doesn't have enough memory. It complains this sometimes. So, we ended up using a DGS macbook. It was the one projecting the KAGRA video in the parking area. Please do not take or move this macbook until the next notice from the REFL table.

Oshino-san and I are working on a permanent solition.

IMC REFL HWP rotator is back online on k1ctr8.

IFO REFL HWP motor is now connected to the CH2 on the same driver as the IMC REFL HWP.

Here is the HWP motor summary:

	Computer to ssh	Channel	Command
IMC REFL	k1ctr8	CH1	agilis_control.py 1 1 100
IFO REFL	k1ctr8	CH2	agilis_control.py 1 2 100
IFO AS	k1ctr9	CH1	agilis_control.py 1 1 100
PSL	I forgot

* 100 is an example step size
* agilis script is /opt/rtcds/userapps/release/cds/common/scripts/agilis/

HWP can be driven from MEDM now.

A MEDM screen can be launched as "sitemap -> SYS -> HWP motor"

Related EPICS channels are defined in k1grdconfig (K1:SYS-HWP_***).

A backend script is /opt/rtcds/userapps/release/sys/k1/scripts/medm_hwp.sh

This script works well only on k1ctr*

CR and CRLF as newline should be done away...

Another motorized HWP was added on the REFL_WFS path as reported by Eleonora (see klog 12121). Here is the updated table. YamaT MEDM screen was also updated (sitemap => SYS => HWP motor).

	Computer to ssh	Channel	Command
IMC REFL	k1ctr8	CH 1 Axis 1	agilis_control.py 1 1 100
IFO REFL	k1ctr8	CH 1 Axis 2	agilis_control.py 1 2 100
IFO REFL WFS	k1ctr8	CH 2 Axis 1	agilis_control.py 2 1 100
IFO AS	k1ctr9	CH 1 Axis 1	agilis_control.py 1 1 100
