APEX - Foreseen Changes

  • ZEUS-2: Pending successful commissioning, the redshift (z) and Early Universe Spectrometer (ZEUS-2) may be offered as a PI instrument during future periods. ZEUS-2 is a broadband spectrograph covering 7 telluric windows covering 200 to 850 µm. For details, see Ferkinhoff et al. (2010).
  • Pending successful commissioning, a new single pixel 230 GHz receiver with dual polarization, sideband separated 8 GHz bandwidth per sideband may be offered as of Period 100.
  • If the APEX agreement is extended beyond Period 100, a major telescope upgrade programme will start at the end of 2017. This may result in the telescope being unavailable between November 2017 and April 2018. Time critical observations in this period will not be accepted.
