CMS Derogation Request Due to Radiation
- The CMS experiment requests a partial derogation for cables with respect to ionizing radiation resistance as described in IS 23. For all areas of the CMS experiment exposed to a dose rate of less than 200 Gy/10 y, no specific radiation requirements and testing should be necessary. For all areas above this value, the calculated value for the dose rate (multiplied by an adequate uncertainty factor) should be the basis for the radiation requirement as in IS 41.
