Report on the B23 bread-board Prototype Integration @ESO for optical warm tests

Abstract

The scope of the breadboard B23 prototype is to setup the optical chain (OMT+FH+Filters+Lens) to perform beam measurements to provide a full assessment of the extended frequency range technical capabilities to demonstrate the feasibility of the development of B23 cartridge for ALMA. On November 2015 the breadboard was integrated and setup to perform warm beam tests with the beam scanner at ESO. The pre-integration @ INAF and the integration @ESO was under the responsibility of INAF/IASF-bologna. The iALMA-TEC-ICD-IAB-001-H [AD1] interface control document reports all the information about the entire prototype system, including design solutions and configurations.
