a. The method adopted for predicting the influence of the radiation environment on gravity-wave interferometric experiments shall be agreed with the customer.
NOTE The method adopted for predicting the influence of the radiation environment on gravity-wave interferometric experiments is normally based on a detailed radiation transport calculation, or if a simplified approach is used, the level of error in the prediction is be estimated in order to ensure that it is within the accepted margins defined for the project.
b. The prediction shall be used to assess the noise introduced into the instrument as a result of the incident radiation:
1. changing the charge of the free-floating test mass;
2. acting as a source of energy to change the thermal conditions of the cryogenically cooled test mass;
3. changing the critical temperature of superconducting materials.
