High-Power Ferro-Electric Fast Reactive Tuner
Ilan Ben-Zvi, Alejandro Castilla, Alick Macpherson +1
We present a novel design of a FerroElectric Fast Reactive Tuner (FE-FRT) capable of modulating Mega VAR reactive power on a sub-microsecond time scale. We show detailed analytical…
Partial Meissner effect measurement by a superconducting magnetic flux lens
A. Ivanov, T. Koettig, A. Macpherson
Magnetic flux trapping in the Meissner transition of superconducting radio frequency cavities can substantially increase dissipation which impacts cryogenic costs and necessitates…
Prediction of Beam Losses during Crab Cavity Quenches at the HL-LHC
Robert Apsimon, Graeme Burt, Amos Dexter +10
Studies of the crab cavities at KEKB revealed that the RF phase could shift by up to 50o within ~50 us during a quench; while the cavity voltage is still at approximately 75% of it…
RF Systems
P. Baudrenghien, G. Burt, R. Calaga +7
Chapter 4 in High-Luminosity Large Hadron Collider (HL-LHC). The Large Hadron Collider (LHC) is one of the largest scientific instruments ever built. Since opening up a new energy…
Design, Implementation and First Measurements with the Medipix Neutron Camera in CMS
Dorothea Pfeiffer, Austin Ball, Alan Bell +13
The Medipix detector is the first device dedicated to measuring mixed-field radiation in the CMS cavern and able to distinguish between different particle types. Medipix2-MXR chips…
Fast Beam Conditions Monitor BCM1F for the CMS Experiment
A. Bell, E. Castro, R. Hall-Wilton +8
The CMS Beam Conditions and Radiation Monitoring System, BRM, will support beam tuning, protect the CMS detector from adverse beam conditions, and measure the accumulated dose clos…
