• 28 Participants at 128 Participants at 1stst POCPA in Trieste POCPA in Trieste ((19-21 May, 200819-21 May, 2008))

• Main Topic: Reliability and Adopted solutionsMain Topic: Reliability and Adopted solutions• 8 presentations on the Main Topic; 8 on the status of 8 presentations on the Main Topic; 8 on the status of

some Facilitiessome Facilities• Few comments from the Round Table & Conclusions:Few comments from the Round Table & Conclusions:

– “Much better than Conferences, we are all here”– “Good idea, familiar atmosphere, speak openly, getting many

information in an informal way”– “Perfect as it is: the best thing is to talk about problems;

keep it informal”– “Keep it limited to Particle Accelerators” and no Companies– Two days every two years is good– Send a message from the Community to let companies that

they are “monitored” and they do not face single customers
