TL;DR

This paper presents a prototype straw-based muon detector module that is cost-effective, maintains its geometry under pressure, and is suitable for large-area collider experiments due to its radiation hardness and adjustable operation mode.

Contribution

It introduces a novel straw tube module design that is scalable, pressure-resistant, and optimized for large-area muon detection in collider experiments.

Findings

Prototype module maintains dimensions up to 4 bar pressure.

Design allows construction of large-area detectors with low cost.

Detector exhibits good radiation hardness and operational flexibility.

Abstract

The article considers a prototype module with sensitive dimensions of 2 x 0.5 m2 based on 2 m long straw tubes which preserves its geometrical dimensions up to the pressure of 4 bar independently of the ambient temperature and humidity. The suggested technique provides a possibility of constructing relatively low-cost planar modules by using straw tubes as long as needed for constructing large area detectors at colliders or other field experiments by assembling them in a common coordinate detector with a user-specified acceptance. The distinguishing feature of a detector is its good radiation hardness, low radiation thickness and a possibility of optimizing the detector operation mode in a large range of gas pressure.
