The Tenerife Experiment was a Cosmic Microwave Background (CMB) experiment built by Jodrell Bank (then known as the Nuffield Radio Astronomy Laboratories) of the University of Manchester in collaboration with the Instituto de Astrofisica de Canarias (IAC). It was the first CMB experiment to be installed and run at the Observatorio del Teide in Tenerife, starting operations in October 1984, and running with various upgrades and additional experiments until 2000.

  • The Tenerife Experiment was a Cosmic Microwave Background (CMB) experiment built by Jodrell Bank (then known as the Nuffield Radio Astronomy Laboratories) of the University of Manchester in collaboration with the Instituto de Astrofisica de Canarias (IAC). It was the first CMB experiment to be installed and run at the Observatorio del Teide in Tenerife, starting operations in October 1984, and running with various upgrades and additional experiments until 2000. It measured anisotropy of the CMB on angular sizes of 5 degrees, about the size of the upper half of the constellation of Orion (from the "belt" to the "shoulders"). To reduce receiver instability, it performed fast between two horns separated by 8 degrees. To remove long term drifts and atmospheric variations, it used a further switch of 8 degrees using a flat mirror in front of the horns. (en)

Per ridurre l'instabilità del ricevitore fu impiegato un radiometro differenziale Dicke che "guardava" alternativamente due antenne separate di 8 gradi. Era composto da tre radiometri operanti alle frequenze di 10,45, 14,9 e 32,5 GHz. Questo permise l'identificazione del segnale di CMB e dell'emissione della Galassia (poiché essi sono a temperature molto simili), in modo da poter eliminare il segnale di provenienza galattica poiché esso decade con la frequenza.
