Hi Hi,

some info on point 2 the size of a zdc

cheers elke

Dear All,

so here just a quick summary of the info we need to get to Bob for his talk.

1. what is the crossing angle we need to have for the high bunch option to avoid parasitic collisions

2. what is the size of a ZDC for EIC

if you look to Nuclear Instruments and Methods in Physics Research A279 (1989) 503-517 a high resolution ZDC would be roughly 0.6 m x 0.6 m x 2.5 m

Of course the width depends also on the z position of the ZDC. The =/-4 mrad neutron cone has at 30 m a transverse size of +/- 12cm

3. what is the size of the lumi-monitor system

4. what is the size for the RP system
---> we should try to have only vertical plots which circumference the beam, the length in z is roughly 5 - 6m

Did I forget something.

cheers elke
