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.
ARTEMIS: In future periods, parallel observations at 450 µm (4 arcmin x 2 arcmin ) may be off ered.
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 99.
