TL;DR

The paper describes the design, construction, and testing of MiniPlug calorimeters for the CDF detector, which measure particle energy and position in the forward pseudorapidity region, enhancing the detector's capabilities.

Contribution

It introduces a novel calorimeter design with pixel-type geometry and reports on prototype performance and cosmic ray testing results.

Findings

Light yield of approximately 100 pe/MIP exceeds design requirements

Successful installation as part of the CDF upgrade at Tevatron

Prototype performance validates the design concept

Abstract

Two MiniPlug calorimeters, designed to measure the energy and lateral position of particles in the (forward) pseudorapidity region of $3.6<|\eta|<5.2$ of the CDF detector, have been recently installed as part of the Run II CDF upgrade at the Tevatron $\bar pp$ collider. They consist of lead/liquid scintillator read out by wavelength shifting fibers arranged in a pixel-type towerless geometry suitable for `calorimetric tracking'. The design concept, the prototype performance and the final design of the MiniPlugs are here described. A recent cosmic ray test resulted in a light yield of approximately 100 pe/MIP, which exceeds our design requirements.
