     - Longitudinal Schottky signal analysis for December 2019 IMP bunched beam cooling experiments. Evaluating the full width at half maximum

Diagnostic Development - Kevin Jordan

Kevin Jordan

   Next two weeks (Dec 9 - Dec 20)

Joe Gubeli

   Previous two weeks (Dec 23 - Jan 3)
     - Isotope Experiment – Reinstalled the camera that images the alignment target.
     - Halo monitor – We finally tracked down the missing $27k that was wire transferred on 10/10/2019. Radiabeam had applied the wrong
       routine code and the funds went to the State Department instead of DOE.
     - ARDDOT – Designed an imager that can be used to replace nearly any CEBAF viewer camera. The only requirement is that those viewers
       have a non-obsolete, limited aperture, viewport. Order the parts for a test setup as well as acquired an insertable assembly from I&C 
       and a viewer cross from the Vacuum Group. Assembled and tested the setup, it works well.
     - HPWS - Design a beam expander and focusing laser setup to tightly focus a laser spot on the thin wire of the scanner. Order,
       assembled, tested and installed the setup. The setup was needed to test Jay Yan’s control and acquisition hardware and software. He was
       able to successfully scan the wires to obtain the three Gaussian distributions. 
   Next two weeks (Feb 17 - Feb 28)
     - HPWS – Work with Jay and others to complete the device and prepare it for installation.
     - ARDDOT – Continue working with Zemax. Start working on a couple of different optical designs that will allow the cameras on the 
       CEBAF SLMs to be in a lower radiation environment. The current beam setup in CEBAF allows for much higher production of radiation at the
       detriment of the electronics in the tunnel.
