The Muon Ionization Cooling Experiment (MICE) is a demonstration experiment to prove the viability of cooling a beam of muons for use in a Neutrino Factory and Muon Collider. The MICE cooling channel is a section of a modified Study II cooling channel which will provide a 10% reduction in beam emittance. In order to ensure a reliable measurement, we intend to measure the beam emittance before and after the cooling channel at the level of 1%, or an absolute measurement of 0.001. This renders MICE as a precision experiment which requires strict controls and monitoring of all experimental parameters in order to control systematic errors. The MICE Controls and Monitoring system is based on EPICS and integrates with the DAQ and Data monitoring systems. A description of this system, its implementation, and performance during recent muon beam data collection will be discussed.

The MICE experiment uses a beam of low energy muons to study ionisation cooling. This beam is derived parasitically from the ISIS synchrotron at the Rutherford Appleton Laboratory. A mechanical drive has been developed which rapidly inserts a small titanium target into the beam after acceleration and before extraction, with minimal disturbance to the circulating protons. One mechanism has operated in ISIS for over half a million pulses, and its performance will be summarised. Upgrades to this design have been tested in parallel with MICE operation; the improvements in performance and reliability will be presented, together with a discussion of further future enhancements.

The MICE experiment uses a beam of low energy muons to test the feasibility of ionization cooling. This beam is derived parasitically from the ISIS accelerator at the Rutherford Appleton Laboratory. A target mechanism has been developed that rapidly inserts a small titanium target into the circulating proton beam immediately prior to extraction without unduly disturbing the primary ISIS beam. The original control electronics for the MICE target was based upon an 8-bit PIC. Although this system was fully functional it did not provide the necessary IO to permit full integration of the target electronics onto the MICE EPICS system. A three phase program was established to migrate both the target control and DAQ electronics from the original prototype onto a fully integrated FPGA system that is capable of interfacing with EPICS through a local PC. This paper discusses this upgrade program, the motivation behind it and the performance of the upgraded target controller.
