Title: Maximum Beam Power and Nominal Beam Losses at S-20

Abstract

The maximum credible beam power values for electrons shown in Table 1 for e{sup -} beams are based on a beam power of 1.8 MW (1.875 x 10{sup 12} e{sup -} at 120 Hz) for an energy of 50 GeV at S-30. Positrons are limited by the positron source damage threshold to an average current of {approx}2 {mu}A, i.e., {approx}10{sup 11} e{sup -} per pulse at 120 Hz on the target [1]. The ratio of e{sup +} at S-1 per e{sup -} on the conversion target is {ge}2. At S-20 the maximum linac energy is 33 GeV, while the HER and LER Bypass beams are limited to 12 and 4 GeV respectively by the BCS.
