“…A significant number of temperature sensors capable of functioning independently of the power status of the experimental apparatus is still needed for safety reasons. The temperature sensors of choice, Platinum Resistance Temperature Detectors (Pt RTDs) have been proven to survive the detector environment (irradiation and up to 4 T magnetic field) and they are also efficiently read out over long cables by using a 4-wire connection [3,4]. Used in the Compact Muon Solenoid (CMS) tracker from the beginning, their number has significantly increased in the design of the Long Shutdown 3 (LS3) CMS detector upgrade [5].…”

As high readout channel density and compact design become the norm for HEP detectors so is the detector cooling at temperatures below the experimental site dewpoint. This increases the importance of humidity and temperature monitoring systems that are also adapted to the detector environment. The proposed systems for temperature and humidity monitoring are developed targeting compactness, cost, and seamless integration to the CMS DSS/DCS systems. Therefore, this paper presents a novel design for a standalone system, able to condition up to 24 temperature sensors. The proposed temperature monitoring system is aimed at many hundreds of RTD sensors with modest space and price requirements. For humidity monitoring, we have identified a potential sensing element and designed, built and tested the conditioning electronics capable of nullifying the capacitance of the long cables.

“…Both sensors can be miniaturized, mass-produced, and read over long distances. However, temperature sensors that can survive inside the detector environment are identified and used [14][15][16] , but not humidity sensors that can be radiation tolerant and satisfy the required performance.…”

Cooling at subzero temperatures and the subsequent monitoring of humidity in the modern Si-based high-energy physics detectors are indispensable but challenging due to space, radiation and magnetic field issues. In this study, a group of relative humidity sensors have been tested for operation reaching high irradiation doses adequate to the inner sub-detectors during the HL-LHC operation. The sensors were exposed to the 24 GeV/s proton beam for a period of 33 days reaching the fluence of 3 x 1016 protons/cm2. The test has demonstrated sensors radiation tolerance at high doses and their ability to provide valid alerts to the detector control and safety systems in the event of any changes in humidity. The irradiation was conducted in a temperature- and humidity-controlled environment. Tested samples were placed in a specially designed cold box able to guarantee an ambient temperature of -20 oC. Throughout the entire test, the compressed dry air was used to keep low humidity levels (around 0 %rh) inside the cold box, and a 100 ppm pre-calibrated gas mixture was used to test the sensors responsiveness before and after the irradiation process. Additionally, an on-purpose designed signal conditioning unit was used to compensate for the cable parasitic effects.
