Foreseen changes regarding La Silla, Paranal and APEX instrumentation and facilities

La Silla

No foreseen changes.

CRIRES:
- The ThAr lamp may be replaced by a UNe lamp in the course of P92.
- Subject to approval of a major upgrade project, the instrument may be taken out of operations for one year starting in the second semester of 2014.

XSHOOTER will probably undergo an intervention lasting 3 months in Period 93 or 94, during which the instrument will not be available for operations. The aim of the intervention is to fix the ADC systems.

VIMOS: A call for public spectroscopic surveys may be issued for VIMOS in the near future,if the instrument upgrade is successful and the observation backlog has been resolved.

It is expected that the 2nd generation instruments MUSE and SPHERE will undergo commissioning in P93.

GRAAL, the adaptive optics module for HAWK-I, is expected to be installed on Nasmyth A early in Period 93.
The installation of the 4 Laser Guide Stars Facility (4LGSF) is expected to take place late in Period 93.
GALACSI, the adaptive optics module for MUSE, is expected to be installed on Nasmyth B early in Period 94.
The installation of the Deformable Secondary Mirror and re-commissioning of the telescope is expected to take place late in Period 94; as a consequence, UT4 will not be available during 2 months.

MIDI will likely be decommissioned during P93.
It is expected that the VLTI Visitor Instrument focus will not be available starting with P93.

Artemis : the installation of this PI instrument is foreseen in the first quarter of 2014. After succesful commissioning, it may be offered to the ESO community.
ZEUS-2: Pending successful commissioning, the redshift (z) and Early Universe Spectrometer (ZEUS-2) may be offered as a PI instrument during Period 93. ZEUS-2 is a broadband spectrograph covering 7 telluric windows covering 200 to 850 µm. For details, see Ferkinho et al. 2010.
