1. SR Update for JLEIC June 8, 2017
M. Sullivan

2. Outline Where we left off after the Collaboration meeting
Photon files
Detector simulation work (Yulia Furletova)
Worked on FCC SR issues in May
Present design looks like it should work at all beam energies
Highest beam energy (Top mass = 175 GeV) is the most difficult – like the JLEIC

3. After the collaboration meeting
Yulia and I connected and I created a file of photons that had scattered from the mask tip 1 m upstream from the IP
She was able to read the file and use it as input to a GEANT4 model of the detector
Detector design details now become important in order to accurately calculate SR backgrounds and to design shielding

4. FCC Week May 28 – Jun 2
Spent most of May working on results for the FCC week and the end of the month
Have found that SR backgrounds can be controlled for all machine energies including the Top energy (175 GeV)
The top beam energy is the most difficult
The Z and WW beam energies have no measurable backgrounds from SR

5. Next steps
Connect with Yulia again and see if the photon file is working as expected
Detector design is now important for further studies
This will include iteration on the beam pipe as well
IR magnet designs are also now needed to make sure the beam pipe is OK
