This presentation will give an overview of the development work at ISIS neutron and muon source, STFC on the Super MuSR project. This project is an upgrade to the existing MuSR instrument at ISIS, which will lead to an improved time resolution and counting rate. An emphasis will be placed on the electrostatic chopper which will produce a ±35kV voltage reversal within 10ns, flipping the...
Selection of single muons is needed for two experiments at PSI. Four +/- 5kV Switches in a bridge configuration provide a +/-10kV potential for switching muons at a 37kHz rate. A successful system was developed and in operation for 20 years. It relies on a flow of FC77 coolant directly on the transistors in the HV switch to remove ca. 1kW of heat. Unfortunately, the switches were destroyed...
