DESCRIPTION:Speakers: Eugene Vishnyakov (P.N.Lebedev Physical Institute of
  RAS)\nWe have employed VEPP-4 synchrotron radiation to measure CCD detect
 or absolute responsivity in vacuum ultraviolet (115-310 nm) spectral rang
 e. The detector is designed in the form of a stainless steel enclosure con
 taining a backside-illuminated CCD to protect the CCD from contamination. 
 The entrance window of the enclosure is a round MgF2 spectral filter trans
 parent for ultraviolet radiation with wavelengths longer than 112 nm. The
  measurements were carried out at Kosmos Metrological Station at the opera
 ting temperature of -100°C on the sensitive surface of the CCD. We utiliz
 ed SPD calibrated silicon photodiode with 1 cm2 sensitive area and a know
 n spectral sensitivity profile as a reference detector. The resultant meas
 urements show a clear CCD responsivity dip near 280 nm\, and a great pote
 ntial to improve the CCD responsivity values using specially designed anti
 -reflection coatings.\n\nhttps://indico.inp.nsk.su/event/24/contributions/
