34. The experiment that motivated Two-Photon effect studies

Mark Jones (Jefferson Lab)

3/24/25, 10:50 AM

A review of the past experiments which measured the ratio of the proton's electron to magnetic form factor at Jefferson Lab. An update will be given on the present experiment to measure the proton's electron to magnetic form factor up to Q2 = 12 GeV2
which will start running at the end of March 2025.

38. Ce+BAF Working Group R&D plan

Joe Grames (JLab)

3/24/25, 11:20 AM

The framework of the Ce+BAF Working Group 3-year R&D plan will be presented, with a special emphasis given to explaining some of the key technical challenges and thereby giving context to the accelerator presentations in this workshop.

42. 22 GeV accelearator plan and physics update

Patrizia Rossi (JEFFERSON LAB), Alex Bogacz (Jefferson Lab)

3/24/25, 11:50 AM

Extending the energy reach of CEBAF up to 22 GeV within the existing tunnel is being explored. Proposed energy upgrade can be achieved by increasing the number of recirculations, while using the existing CEBAF SRF cavity system. Encouraged by recent success of the CBETA Test Accelerator, a proposal was formulated to raise CEBAF energy by replacing the highest-energy arcs with FFA arcs. The new...
