Estimate of the Pbar Yields for the CERN ACOL Project

PDF Version Also Available for Download.

Description

For a check of the yield estimates expected for the new ACOL target station, calculations have been performed for the CERN parameters using the relatively, simple semi-analytical techniques outlined in pbar note 449. These calculations correspond to operation with a 15 cm long, 1 cm radius lithium lens at 750 T/m gradient, and a 6.5 cm tungsten production target. Comparison with the current calculated yield number for the AA with the present target station configuration (10**7 pbars per 10**13 protons, into dp/p = 1.5%) indicates an increase of a factor of 15 using the normal ACOL parameters (dp/p = 6%, ... continued below

As explained in the report, the above lens parameters are not optimized, that is, increases in lens gradient and/or radius will result in an increase in yield, providing the corresponding changes in focal distance, beam line matching, etc. are made.
