Several large-scale laser\u0000interferometric gravitational wave detectors (GWDs) have been constructed\u0000worldwide, with a focus on achieving the best sensitivity possible. However, in\u0000order for a detector to operate at its intended sensitivity, its optics must be\u0000free from imperfections such as thermal lensing effects. In the GEO,600\u0000gravitational wave detector, the beam splitter (BS) experiences a significant\u0000thermal lensing effect due to the high power build-up in the Power Recycling\u0000Cavity (PRC) combined with a very small beam waist. This causes the fundamental\u0000mode to be converted into higher order modes (HOMs), subsequently impacting the\u0000detector's performance. To address this issue, the GEO,600 detector is\u0000equipped with a thermal compensation system (TCS) applied to the BS. This\u0000involves projecting a spatially tunable heating pattern through an optical\u0000system onto the beam splitter. The main objective of the TCS is to counteract\u0000the thermal lens at the BS and restore the detector to its ideal operating\u0000condition. This paper presents the new beam splitter TCS in GEO,600, its\u0000commissioning, and its effect on strain sensitivity. It also outlines the\u0000planned upgrade to further enhance the performance of the TCS.","PeriodicalId":501374,"journal":{"name":"arXiv - PHYS - Instrumentation and Detectors","volume":"40 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141935030","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The electrons are extracted from the\u0000interaction site through a gas gap, where they meet a high electric field where\u0000proportional scintillation occurs. This converts the electron signal into a\u0000light signal, and yields a high electron detection efficiency with a gain of\u0000tens of photoelectrons (PE) per electron. This technique of detecting both\u0000scintillation and ionization gives dual phase xenon TPCs the capability to\u0000distinguish between electronic and nuclear recoils, which is a key part of how\u0000these detectors are able to reach world-leading limits on Weakly Interacting\u0000Massive Particle (WIMP) dark matter. However, not all electrons can be\u0000extracted through the liquid-gas interface, and a constant millimeter-scale gas\u0000gap needs to be maintained, which may be a technological challenge if\u0000dual-phase xenon TPCs are to be scaled up for future dark matter searches.\u0000Furthermore, there is a background of single-electron peaks that follow a large\u0000ionization signal (S2) of unclear origin which may be due in part to the\u0000liquid-gas interface, and limits the sensitivity of these detectors towards low\u0000mass dark matter. In this paper, we demonstrate that a purely single-phase\u0000liquid xenon TPC which produces proportional scintillation directly in the\u0000liquid is still capable of discriminating between electronic and nuclear\u0000recoils, but that the background of single-electrons following an S2 is still\u0000likely unrelated to the liquid-gas interface.","PeriodicalId":501374,"journal":{"name":"arXiv - PHYS - Instrumentation and Detectors","volume":"77 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141935170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
