SMAUG2 experiment - Anthony Harrison // Study of thin Si3N4 windows for the Muon Collider - Valentina Giovinco

10:30 → 11:00 SMAUG2 experiment

SMAUG 2 is following on from the previous Glassy Carbon study of HRM#29, SMAUG 1 and SMAUG 1.5 ‘baby SMAUG’ experiments in HiRadMat. Exploring the materials used for vacuum windows within particle accelerators as we progress to higher beam intensities.
Trying to identify the reason for why previous beryllium windows failed in operation, what are the limits of Glassy Carbon, and what are the limits for Silicon Nitride and their potential use on the Muon Collider.

11:00 → 11:30 Study of thin Si3N4 windows for the Muon Collider

As part of the muon collider study, a thin-beam vacuum window is being developed. It will be required in the final cooling stage of the muon collider. To evaluate the performance of the window, it is necessary to study the tightness at cryogenic temperatures, resistance to burst, and high temperature and beam-induced damage. A bulge test setup has been developed to test thin windows at different pressures and temperatures to cover all operating conditions. Silicon nitride membranes have been characterized at 77K, 293K and 425K.
