As you all know, we have had trouble starting a measurement with a DGS error [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=15567|klog#15567]]. In order to eliminate this confusion during the work, I make the following rules;
 * First, make sure that the VIS_OVERVIEW screen shows '''all green before you start working'''.
 * And after working, be sure to '''make everything green''' before finish your work. This is a kindness for the next operator.
 * The SDF will probably turn red as you work. This means that SDF has detected channel differences during your work. If you accept these differences, please '''take a screenshot and post it in klog''' (e.g. [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=15553|klog#15553]]), but you don't have to post it to revert.

That's all.

General

[Miyo] As you all know, we have had trouble starting a measurement with a DGS error klog#15567. In order to eliminate this confusion during the work, I make the following rules;

  • First, make sure that the VIS_OVERVIEW screen shows all green before you start working.

  • And after working, be sure to make everything green before finish your work. This is a kindness for the next operator.

  • The SDF will probably turn red as you work. This means that SDF has detected channel differences during your work. If you accept these differences, please take a screenshot and post it in klog (e.g. klog#15553), but you don't have to post it to revert.

That's all.

Type-C

  • Set up the old OSTM suspension in the OMC both.

  • [Miyo] We (mainly Ikeda-san) made Type-C guardian. Now we can use ALIGN state. In this state, we only engage the APTICALIGN with ramp time not engage the OpLev DC control according to Nakano-san's advices. klog#15578
