Accelerated ageing tests were performed on four test chambers using high intensity 8 keV X-rays. The effects of varying the following chamber parameters were investigated: strip metal (aluminium, gold), substrate type (Schott S8900, Desag D263) and gas mixture ( Ar DME , Ne DME ). After initial poor ageing results from an MSGC fabricated with aluminium strips on an S8900 substrate, chambers consistently withstood total deposited charge values in excess of 100 mC/cm, with no significant loss of gain.
