1. 10/3/2003Andreas Jansson - Tevatron IPM review1 Tevatron IPM Motivation and overview

2. 10/3/2003Andreas Jansson - Tevatron IPM review2 Why an IPM in Tevatron? Emittance preservation –Directly detect injection matching and emittance blowup. –Continuous emittance evolution e.g. on ramp (complement to FW, fills the low energy gap in SL).

4. 10/3/2003Andreas Jansson - Tevatron IPM review4 Wish-list At injection: Measure beam size turn-by- turn to 10% accuracy (N turn >> 100). On front porch, during ramp and at flat top: Measure average beam size to 3% accuracy or better (follows from first bullet). Measure pbars with protons in machine (but not necessarily measure both particle types simultaneously).

5. 10/3/2003Andreas Jansson - Tevatron IPM review5 Some beam parameters… Intensity: –Protons: 3.5 10 10 - 3.5 10 11 (nominal 2.7 10 11 ). –Pbars: 1 10 10 - 1 10 11 (nominal 2.7 10 10 ). Beam size –Injection: ~1.7 mm –Flat top: ~0.5 mm Bunch separation 396ns (no 132ns operation assumed)
