The Methodology and Implementation of a Real Time Monitoring System for Cryogenic Fridges

TL;DR

This paper presents the design and implementation of a real-time monitoring system for cryogenic refrigerators, enabling remote access and data management based on logs from dilution refrigerators.

Contribution

It introduces the Fridge Real Time Monitoring System (FRTMS), a novel system inspired by previous monitoring setups, with capabilities for log management and remote monitoring.

Findings

Enables near-real-time remote monitoring of cryogenic fridge logs

Automates log backup and formatting for database upload

Improves reliability and accessibility of cryogenic fridge data

Abstract

Inspired by the dilution refrigerator and magnet monitoring system developed for HAYSTAC at Yale University, Speller Lab at Johns Hopkins University developed the Fridge Real Time Monitoring System (FRTMS). The FRTMS accesses logs saved locally by the dilution refrigerator, saves these logs to various backup locations, edits the logs into a format for upload to a MySQL database, and allows the logs to be remotely monitored in near-real time.
