Fast PIN-diode beam loss monitors at Tevatron

The article is devoted to results of fine temporal structure of particle losses in the Tevatron ring obtained with use of fast beam loss monitors (BLM) based on PIN-diodes. In the Tevatron fixed target operation regime, these monitors were able to distinguish proton losses from bunches spaced by only 19 ns. Besides measurements of main characteristics of the BLMs, we studied the proton losses over 10 decades of time intervals – from a dozen of minutes to a dozen of nanoseconds. Due to huge dynamical range and fast response the PIN-BLMs perfectly fit the task of the beam loss detection at the Tevatron collider upgrade with as small as 132 ns bunch spacing.
