G U I D E L I N E S F O R B E A M R E Q U E S T S ========================================================= A T T H E P S A N D T H E S P S =========================================== Together with your beam request for the PS East Hall beams or the SPS beams, additional informations on your experiment or test beam activity should be given. The additional information is of particular importance for new experiments or test beam users who were not using PS East Hall or SPS beams before. If unsure on some items or don't know yet, please contact the SPS/PS Coordinator. Please read the guidelines below and consider the relevant items in your beam request. YOUR EXPERIMENT OR TEST BEAM ACTIVITY AND YOUR BEAM REQUEST ============================================================= o NAME of the experiment or test beam activity (e.g. NA60, COMPASS, ALICE-PHOS, OPERA, RD42) o PURPOSE of the experiment or test beam activity (e.g. physics, prototype tests, detector/electronics R&D) -> Give a brief description what the experimental programme will be or what the aim of your test beam programme will be. o RESPONSIBLE PERSON (e.g. run coordinator, test beam coordinator, spokesperson) Name, home institute, address, (CERN) phone, fax, e-mail -> This usually is the run coordinator, test beam coordinator or spokesperson of the experiment. o CONTACT PERSON AT CERN (if different from responsible person) Name, home institute, address, (CERN) phone, fax, e-mail -> If the responsible person is usally not at CERN, please give the name of a contact person who is usually resident at CERN, if possible. o REQUESTED BEAM TIME (e.g. 1 week, 1 month) -> Requested beam time at the PS East Hall of more than 14 days per year and at the SPS of more than 7 days per year needs to be recommended and approved by the relevant CERN scientific committee (e.g. SPSC, LHCC and Research Board). IF YOUR REQUEST EXCEEDS 14 DAYS/YEAR AT THE PS OR 7 DAYS/YEAR AT THE SPS: ------------------------------------------------------------------------- -> Has your beam request already been submitted/recommended/approved to/by a committee? Please refer to committee minutes, if possible. FOR A BEAM TEST THAT IS NOT RELATED TO ANY CERN EXPERIMENT/PROJECT ETC.: ------------------------------------------------------------------------ -> Is your test related to an APPROVED experiment or R&D-project of another laboratory in a CERN member/observer/non-member state, or is it an individual test? What are your requirements in terms of manpower/material from CERN? BEAM REQUIREMENTS =================== o PARTICLE TYPE, MOMENTUM, POLARITY, INTENSITY, BEAM SIZE etc. (e.g. muons, electrons, hadrons, 10^4 particles/spill etc.) -> A variety of particle types, intensities and particle densities from secondary or tertiary beams is available. Please have a look to the descriptions of the different beam lines that you can find on the web. As neighbored beam lines might share secondary beams from the same target, there are correlations between those beam lines. At the PS East Hall, T9/T10/T11 are using the same (North) target. At the SPS, X5/X7, H2/H4 and H6/H8 are making use of beams from the same target, respectively. Only users whose beam requirements are compatible are able to run in parallel in those beam lines. Thus, please give as much information as possible here, e.g. if you need hadrons(pions) or electron enriched beam. Please also specify if you need a particular polarity (e.g. negative pions only) or if the polarity doesn't matter. The choice of polarity can have a big impact on the scheduling. o PREFERRED BEAM LINE (e.g. T7,T8,T9,T10,T11 at the PS or X5,X7,H2,H4,H6,H8 at the SPS) -> Information on the characteristics of the various beam lines in the PS East Hall (T7,T8,T9,T10,T11) and the SPS West Area (X5,X7) and SPS North Area EHN1 (H2,H4,H6,H8) can be found on the web. Some beam lines are more suited to certain particle types and energies than others, e.g. the H4 beam is the best beam line for high energy electrons (up to about 300 GeV). If you would like to use a preferred beam line, please indicate. TIME CONSTRAINTS =================== o PREFERRED and EXCLUDED TIME OF THE YEAR (e.g. early, late, July/August, NOT in July, NOT before June) -> Please indicate the preferred running period. Please also give your excluded running periods if any, e.g. NOT in July due to conferences or NOT before June because your detector might not be ready. This information helps a lot to solve conflicts if the schedule becomes tight. EQUIPMENT AND INSTALLATION ============================ o TYPE, SIZE AND WEIGHT OF DETECTOR (e.g. Silicon detector, RPCs, calorimeters) -> Please indicate (if possible), amount of radiation/interaction length. If you have a "transparent" detector (e.g. tracking detector), other parasitic users further downstream may be able to use the beam as well. This usually is more difficult if your detector is a calorimeter where only muons get through. o SPACE AND ELECTRICAL POWER REQUIREMENTS (e.g. length along beam line, width, power consumption) -> Space along the beam line could be limited by additional Cerenkovs, mobile beam instrumentation, magnets that you might not find on drawings. If your electronics has a large power consumption, please indicate the approximate power needed (kW). o ADDITIONAL INSTALLATIONS (e.g. Magnets, Platforms, Cerenkovs for particle ID) -> If you need additional installations, e.g. magnets etc. please take in mind that they need cooling water, cables and power supplies. Although a magnet apparently looks installed in a beam area, it might not be operational as e.g. cables or power supplies might be in use elsewhere. A limited number of Cerenkov detectors for particle ID is available. Please indicate early enough if you intend to use them. o TIME NEEDED FOR INSTALLATION/DEINSTALLATION -> The allocated time period includes the time needed for installation/deinstallation. It is assumed that you remove your equipment completely from the beam area and the electronic huts BEFORE your time period has been finished and the hand-over to the next user takes place. Please contact the SPS/PS Coordinator if you want to keep equipment in the beam area after your time period is finished. SAFETY HAZARDS ================= o FLAMMABLE/POISONOUS GASES (e.g. Ar/CH4 90/10) -> If you need to use any gases, please indicate the gases and give their mixture even if you believe that the mixture is non-flammable. CERN rules on flammability are in general more strict and gases might be considered flammable at CERN but non-flammable elsewhere. Please contact the EP-FGSO (EP division Flammable Gas Safety Officer) if you want to use flammable mixtures or if in doubt. o PRESSURE/VACUUM/CRYOGENICS (e.g. gas detectors under pressure, LAr detectors) -> Such equipment might need additional technical safety inspections or tests. o LASER (e.g. UV-lasers for calibration purposes, N2-, Nd:YAG-lasers) -> Any lasers and in particular UV-lasers require special protection means depending on their energy or power. These could be protecting tubes or special glasses for people working with them. Please contact the TIS-RP group (radio protection group) if you want to use a laser other than a laser pointer. o IRRADIATED MATERIALS AND SOURCES (e.g. detectors or any materials that have been irradiated) -> If you intend to make an irradiation of material or want to use any irradiated and activated materials, the TIS-RP group should be contacted well in advance. Irradiation of materials in general requires an IRRADIATION PERMIT (Radiation Protection Procedure PRP 17, form available from TIS-RP or as EDMS document ID 338324) Depending on the expected activation, a detailed work and dose planning might be required to avoid unnecessary high personal doses. Use of strong sources or radioactive gases, e.g. Kr83 for calibration purposes also might require additional safety means. => After your beam request has been submitted, you may be asked by the SPS/PS Coordinator to supply more informations if necessary.
