Introduction n History Program inception 1986 u Feasibility studies 1988 u fund of 8 M DM by the Ministry of Economics, Trade and Technology, NRW 1989 u Poltical problems, between AIRUB and industry and reunifcation 1992 u Several attempts meanwhile u 8. 10. 2005 2

History (cont. ) Ministry of School, Education, Science and Research (MSWWF), NRW grants new funds 1997 u HPT comes to Bochum 1999 u Replacing of the old driving system 2001 u Replacing of the old software system 2002 u First pointing tests 2003 u Shipment to Chile June 2005 u 8. 10. 2005 3

Technical concept n n n direct-motor driven roller screw, accuracy 10 nm weight of a single leg is about 200 kg Optical configuration 1. 5 m primary mirror u Focal ratio f/D = 2. 5 u Field rotation 45 deg u 8. 10. 2005 4

M 1 n n 55 mm thin meniscus, weight 120 kg, 1. 2 t/sqm VLT 10 t/sqm an actively controlled primary which consists of a thin Zerodur meniscus that is permanently fixed to a CFRP grid structure 8. 10. 2005 5

M 2 a secondary whose support legs are also designed as a Hexapod to compensate for gravitational deformation 8. 10. 2005 6

Code generation n Automatic generation of an Component from a given IDL, including *. h and *. cpp files u Makefile u *. body function body u *. xsd and *. xml files for CDB u QT GUI u talk tomorrow by Martin Paegert 8. 10. 2005 7

Software 8. 10. 2005 8

CCD software n Different types of camera hardware but only one ACS module Camera factory class u One interface class u Class structure: 8. 10. 2005 9

CCD: class structure 8. 10. 2005 10

ACS in CCD´s real life: What is in use now? n Monitoring possibilities u n n 8. 10. 2005 Triggering of applications Data transfer via sequences (later via Notification Channel or bulk data channel) 1 Module – 3 CCD camera manufacturer (+ 1 simulation) – 4 different configurations 11

Next steps n n n After infrastructural problems are solved, assembly of telescope and electronics Commissioning Science verification 8. 10. 2005 12

The usage of ACS n n n 8. 10. 2005 Easy to integrate peripherials (GPS clocks, Game pads, Web. Cams, CCDs, Motor control units, DIO and AIO boards) Easy to develop GUIs with Python and Qt MS-Windows drivers u Directly ported to Linux u Using an ACS Version ported to Cygwin 13

Conclusions n n n 8. 10. 2005 ACS does what is required Sharing code among projects Discussions between the groups using ACS 14
