What I did

• I replaced the satellite boxes for the PRM IM OSEMs to modified ones.
  • The modified satellite box has additional 100 nF capacitor in the transimpedance amplification stage.
  • The old ones have been returned to AEL staffs.

  • Serial numbers of the related satellite boxes

    	Old	New
    IM (V1, V2, V3, H1)	S1604895	S1807625
    IM (H2, H3)	S1604892	S1807626

• I measured the spectra of the IM OSEMs with both the new and old satellite boxes.
  • The new satellite boxes showed smaller noise levels at high frequencies without any malfunction.
  • 

Side works

• I picked up the jigs for packaging the TMS-VIS from the X-end.
• Broken traverser drivers (for PRM and PR3) were taken out of the mine.
  • These two kinds of stuffs are ready for being sent to Mitaka.

Next steps

• Satellite box replacement for PR2 IM OSEMs
• BO implementation for remote switching of the PR stepper motor drivers
• Update of the information of the DGS rack configuration on the wiki
