8. Objectives and requested budget • Our objectives were chosen considering: • Needs of CTA collaboration • CTA schedule • Our previous work • Our expertise • Our links with industry 8/10

9. Identifying CTA needs with UCM-ELEC objectives (I) PMTs are likely to be the first option, but today there is only ONE company able to provide suitable PMTs to CTA. Solid state photodetectors (mainly GAPD) evolve very fast, and have been identified as a backup option. W. Hofmann • Task 2 is coming in the right moment, with the right objectives and with well prepared and coordinated people. • Furthermore, • There is a strong interest within the particle physicist community in GAPDs and other solid state photodetectors. • There are many opportunities of quality research and technology transfer within this field LATEST NEWS (Cracow meeting)

10. Identifying CTA needs with UCM-ELEC objectives (II) We are about to obtain ENAC qualification for our lab. This will enable us to offer certificates of CEM and reliability compliance.
