21 Shielding objectives

The basic principle of radiation protection is the ALARA (As Low As ReasonablyAchievable) principle which states that exposure to any person should be kept as lowas reasonably achievable At SESAME the ALARA principle is applied by guaranteeingthe radiation limits for non‐exposed workers (1mSvy corresponding to 05mSvh for2000 working hours per year) except in controlled areas where access will not bepossible during operation

The number of electrons per year stored in the storage ring is estimated as (a 400mAstored beam current in the 1322 m long storage ring corresponds to 11 1012electrons stored)Normal operation3 injections per day 250 days operation per year 862 1014 electronsyear

Unwanted beam tripsMean time between failure = 24 hours 275 1014 electronsyear

Accelerator RampD program1 day per week 10 injections per day 393 1014 electronsyear

Total number of electrons injected per year 15 1015 electronsyear


The following beam loss distributions have been assumed for the shieldingcalculations of the storage ring

‐ 80 (303mW) of the total losses in any single point in the injection area‐ 10 (379mW) of the total losses in any single point in any other point alongthe storage ring

We use this local loss distribution pattern to calculate both average dose ratesover one year (total loss power 379mW) and to calculate the integrated dosein case of a total beam loss (total energy 441 J)

1- 1m OC plus 15 cm of lead in thickness on the ratchet end walls will fulfil our needs2- 1m OC for the Ratchet side wall with increasing the wall thickness in the injectionarea (13 and 135 m) towards experimental hall and 08 m thickness of ordinaryconcrete for inner storage ring shielding wall is enough and 125m in the injection area3- 1m OC (double overlapped layers) for the ring roof tunnel except 15m (tripleoverlapped layers) for the injection area4- 20cm tungsten alloy (19gcc) safety shutter (only one safety shutter) GB raytracing collimation needed5- PE if needed to be added

6 Storage Ring Tunnel Recommendations


Finally SESAME general strategy during commissioning or normal work1- Start with mentioned (Initial) thicknesses for both concrete and the lead2- Monitor measuring instantaneous effective dose rates passive area monitors will also be used to integrate doses in various areas and evaluate during commissioning via complete controlled system particularly for the microtron3- Extra thicknesses will be added if needed to get non radiation areas (le 05microSvh coming only from radiation losses however keeping in mind there is any way the background which is not included in our estimations) looks like

a- Service areab- Storage Ring Roof c- Booster Roof d- Experimental Halle- Inside the inner booster shielding wall

4- Keeping some areas as controlledsupervised areas (gt 05microSvh)
