An RF Beam Position Measurement Module for the Fermilab Energy Doubler

Abstract
This paper describes the design, realization and performance of the RF Beam Position Measurement Module designed for the Fermilab Energy Doubler. This module measures beam off-axis position and intensity over a 60db dynamic range. For 20 or more contiguous 53MHz beam bunches, the unit will derive a position signal for 108 to 1011 protons per bucket with a position accuracy of ±0.5 mm. Also, the unit will measure the position of 1010 or more protons in a single isolated rf bunch. A beam intensity signal is also generated for triggering purposes. Since 220 of these modules are to be built, cost and performance were optimized. The entire unit is housed in a 1-wide NIM module.
