2017-Mar-03 Diagnostic Development Biweekly Report

Kevin:

• I worked on CRADAs trying to get $ in house
• Started the review of SBIR titled CNT wires for HEP...
• Also data acquisition for the IMP project & visa application
• a few days leave to attend the AVS meeting in San Diego

Joe G:

• Telecentric imager. Figured out why this imager didn’t work when we installed it in CEBAF. I&C had though that the voltage output of the illuminator was 24V. It is instead 12V. We will need about 42mA for a nice bright image with the larger 2-3/4CF viewport. This imager is really designed for this type of viewport and I believe we will need to wait till after this run so we can change out the viewport.
• Non-telecentric imager. Works well with either viewport. Did find that the camera that we had used for radiation damage test appears to be radiation damaged.
• GTS LDRDS. Kevin repaired the BNNT foil and we installed the fork assembly in the chamber. I’ll work on adding the other flanges to the chamber today.

Mike T:

• I took one morning of leave on 28 Feb
• I spent most of my past two weeks doing the following things, in approximately decreasing order of effort:
  • Finishing and transmitting the requirements for the dogleg calculator algorithms to Dennis Turner
  • Examining use cases for the dogleg calculator to ensure that operator-driven features were appropriate
  • Initiating discussions with Eugene Chudakov and Richard Jones about a prospective gamma harp for Hall D
  • Formulating test plans to demo the dogleg calculator functions G and diagnose optics issues in 2R
  • Continuing consultation with Brandi on Hall B procedures and dead-reckoning steering for CLAS12
  • Discussions with visitor Timothy Maxwell from SLAC on beam diagnostics, puzzles and solutions
  • Preparation for late March presentation to CLAS12 Collaboration Meeting
