Descripción:
In this document, as consequence of 23mmdifference in height between the ALMA and LLAMA cryostats (NACOS-NASMYTH-B_24Feb2017_23mm-OpticalAlignment-change from J. Kooi), some parts of NASS assembly had to be updatedin order to avoid this 23mm mismatch. The parts that had to be updated are:· LLA-NFL-NAS-116 (NAS-CABIN-BFL CRYOSTAT SUPPORT TUBE)· LLA-NFL-ATB-101 (ALIGNMEMTTEMPLATE - CABIN-B FL)· LLA-NFL-NAS-117 (ALIGNMENTTEMPLATE LINK I)· The LLAMA cryostat has to bemoved down by 23mm. This was already checked in the Nasmyth B cabin layout andthere are no contact or interference problems with other parts or sub-systems. This design modification correspond tothe AI 201704-11 discussed during the NACOS MRR performed in Sao Pablo, Brazil,in 6th and 7th of April 2017.
