A problem is the contaminated water including the atomic nucleus which relatively has a long half-life time such as 90Sr, 137Cs generated from 235U used for nuclear fuel in particular. Particular, since 90Sr has a long biological half-life time (49 years), it is dangerous to cause internal exposure. Therefore, real-time 90Sr counter is required. It is relatively easy to identify a nucleus emitting gamma ray. But it is more difficult to identify a nucleus emitting pure beta ray such as 90Sr. Typically, measurement of a radioactivity absolute value of 90Sr takes a month at least to give a result. At first, we aim to identify 90Sr/137Cs by threshold type Cherenkov detection. It needs radiator which has less than 1.0492 of refractive index for identification 2.28 MeV of maximum kinematic energy of beta ray from 90Sr and 1.17 MeV of maximum kinematic energy of beta ray from 137Cs. Recent, The material satisfying this request does not exist expect the silica aerogel. We produced prototype and evaluated performance. We achieved 103 of Sr/Cs detection efficiency ratio, 10-3 Hz/ Bq of 90Sr sensitivity at one minute.

Abstract submitted: <https://indico.cern.ch/event/192695/call-for- abstracts/my-abstracts>. Status of your abstract: <https://indico.cern.ch/event/192695/call- for-abstracts/306/>. See below a detailed summary of your submitted abstract: Conference: Tipp 2014 - Third International Conference on Technology and Instrumentation in Particle Physics Submitted by: Submitted on: 27 February 2014 16:24 Title: Development of a new fast shower maximum detector based on micro channel plates photomultipliers (MCP-PMT) as an active element. Abstract content One possibility to make a fast and radiation resistant shower maximum (SM) detector is to use a secondary emitter as an active element. We present below test beam results, obtained with different types of the photo detectors based on micro channel plates (MCP) as the secondary emitter. The SM time resolution - we obtained for this new type of detector is at the level of 20-30 ps. We estimate that a significant contribution to the detector response originates from secondary emission of the MCP. This work can be considered as the first step in building a new type of calorimeter based on this principle. Summary We made measurements with different types of MCP PMT as shower maximum detector. The measurements were performed at the Fermilab Test Beam Facility with 120 GeV/c primary proton beam and 12 GeV/c and 32 GeV/c secondary beams. We obtained time resolution for the SM detector based on Photek 240 at the level of 20 – 30 ps. The SM detector, based on the Photonis MCP-PMT, also achieves a very good TR, ~35 ps. We feel that this level of performance, even with a large MCP pore size (diameter ~25 μm), enables the development of SM detectors for collider experiments at a potentially much reduced cost. The success of the LAPPD project [2, 4] in developing affordable MCP’s is encouraging in this respect. More savings are possible if it can be shown that bare MCP’s without an associated photocathode, can give similar timing performance. We plan on performing a future beam test that can resolve this issue.

Dear Jochen and Max, The abstract submission will be closed tomorrow, Friday February 28 and we would like to give you some further information to complete the rating of all abstracts. We expect to have in your session 15 talks of 20 min, but we will only finalise this number after all abstracts have been rated. It is possible that we will increase the number of slots in your session as there is still room in the overall programme. Therefore, we ask you to propose for talks all the abstracts that meet your requirements for a talk, as we can always reward a poster presentation to the ones we cannot accept as a talk. Ideally, we would like to receive a ranking list to facilitate the assignment of the exact number of talks to each track. We would appreciate if you could complete the rating by Wednesday March 12. Thanks in advance for your kind cooperation, looking forward to seeing you in Amsterdam, Jan Visser on behalf of the local organising committee
