The Integrable Optics Test Accelerator (IOTA) is a storage ring at the end of the Fermilab Accelerator Science and Technology (FAST) facility. The complex is intended to support accelerator R&D for the next generation of particle accelerators. The IOTA ring is currently operating with 150 MeV electrons injected from the FAST Linac and will also receive 2.5 MeV protons from the IOTA Proon Injector currently be installed. The current instrumentation and results along from the first electron commissioning run will be presented along with future plans.

Direct µ->e conversion requires resonant extraction of a stream of pulsed beam, comprised of short micro-bunches (pulses) from the Delivery ring (DR) to the Mu2e target. Experimental needs and radiation protection apply strict requirements on the beam quality control and regulation of the spill. The objective of the Spill Regulation System (SRS) is to maintain the intensity uniformity of a stream of ~25K pulses as 1012 protons are extracted at 590.08kHz over a 43msec spill period. To meet the specified performance, two regulation elements will be driven simultaneously: a family of three zero-harmonic quadrupoles (tune ramp quads) and a RF Knock-Out (RFKO) system. The SRS will use two separate control loops to control each regulation element simultaneously. It will be critical to coordinate the SRS’ processes within the machine cycle and within each spill interval. The SRS has been designed to have a total Gain-Bandwidth product of 10KHz, which can be used to mitigate several sources of ripple in the spill profile.

Fermilab is undertaking the development of a new 800 MeV superconducting RF linac to replace it’s present normal conducting 400 MeV linac. The PIP-II linac warm front-end consists of an ion source, LEBT, RFQ and MEBT which includes an arbitrary pattern bunch chopper, to generate a 2.1 MeV, 2mA H beam. This is followed immediately by a series of superconducting RF cryomodules to produce a 800 MeV beam. Commissioning, operate and safety present challenges to the beam instrumentation. This paper describes these beam instrumentation challenges and the choices made for PIP-II.
