Nanometer BPM Mini-Workshop

KEK, Building number 4 - first floor (unless otherwise noted)

March 10 – 12, 2003

Goal:

The purpose of the mini-workshop is to evaluate possible studies and discuss experiments using cavity BPM’s in the ATF extraction line. Possible experiments include:

1) demonstration of 2 nanometer position resolution

2) demonstration of 100 nanoradian beam tilt resolution (and 100 nanoradian trajectory tilt resolution)

3) direct measurements of BPM relative mechanical motion using the beam

4) stabilization of mechanical motion and validation using the beam and a witness BPM

5) demonstration of nanometer resolution with a multi-bunch beam
6) fast feedback stabilization of a multi-bunch beam

7) demonstration of component stabilization, (i.e. focusing magnets) and validation using beam.
