The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is an interferometric radio telescope at the Dominion Radio Astrophysical Observatory in British Columbia, Canada which consists of four antennas consisting of 100 x 20 metre cylindrical parabolic reflectors (roughly the size and shape of snowboarding half-pipes) with 1024 dual-polarization radio receivers suspended on a support above them. The antenna receives radio waves from hydrogen in space at frequencies in the 400–800 MHz range. The telescope's low-noise amplifiers are built with components adapted from the cellphone industry and its data are processed using a custom-built FPGA electronic system and 1000-processor high-performance GPGPU cluster. The telescope has no moving parts and observes half of the sky each day as the E

Es ist Teil des Dominion Radio Astrophysical Observatory (DRAO) und steht im ländlichen British Columbia (Okanagan Valley bei ). (de) カナダ水素強度マッピング実験（Canadian Hydrogen Intensity Mapping Experiment: CHIME）は、カナダ、ブリティッシュコロンビア州にあるドミニオン電波天文台に建設された電波干渉計で、長さ100メートル、幅20メートルの円筒形放物面反射鏡（スノーボードハーフパイプのサイズとほぼ同じ大きさ）4基で構成されている。1024個の両偏波電波受信機が、円筒形の反射鏡の焦点部分に吊り下げられている。アンテナは、400〜800MHzの範囲の周波数の電波を受信することができ、過去の宇宙に存在した水素原子が放つ電波を主要な観測対象として想定している。望遠鏡の低ノイズアンプは、携帯電話に使われる民生品を活用して構築されており、そのデータは、専用設計のFPGA回路と1000プロセッサからなる高性能GPGPUクラスターを使用して処理される。望遠鏡には可動部分がなく、地球が回転するのに合わせて空を掃くことができる。また、近年では高速電波バースト（FRB）の観測で多くの成果をあげている。 CHIMEは、ブリティッシュコロンビア大学、マギル大学、トロント大学、およびカナダ国立研究評議会が運用するドミニオン電波天文台の協力で運用されている。2017年9月7日に、望遠鏡に初めて天体の信号を導くファーストライト式典が開催され、望遠鏡の試験観測が開始された。 (ja) Il Canadian Hydrogen Intensity Mapping Experiment (CHIME) è un radiotelescopio interferometrico situato presso il (DRAO) nella Columbia Britannica, in Canada. Consta di quattro semi-cilindri di 100 x 20 metri su cui sono installati 1024 ricevitori radio a doppia polarizzazione sensibili alle frequenze tra 400-800 MHz . Lo scopo principale del progetto è approfondire la conoscenza cosmologica della struttura dell'universo giovane, dell'energia oscura e del modello standard Lambda-CDM, che meglio riproduce le osservazioni della cosmologia a seguito del Big Bang. Il telescopio è stato inaugurato il 7 settembre 2017.
