May 10, beam to HTP

(return)

Bismuth beam to HTP for study of radiation hardness of new type of scintillators. The goal was to deliver maximum integrated intensity, similar to December 7, 2019. The old settings were giving good spot on target, but the measured transmission was only 45%, mainly due to large beta function in TH4 area. New setting (2020-05-10_23-16-18_SIS18_SLOW_HTP_20200414_184911.C1.txt) improved the transmission to almost 100%. Here is the view of the new optics:
