A method for operating a magnetic resonance facility is proposed. At least one semiconductor structure is inventively deposited on the carrier plate and forms at least one photodiode, whereby the semiconductor structure at least partly absorbs light impinging on the carrier plate. The example valve assembly includes first valve trim including a first valve stem operatively coupled to a first closure member, the first closure member to engage one of the seating surfaces to control fluid flow between the inlet and the outlet during normal operation. When control information indicates, an instruction is sent from the cache to the CPU if a cache hit occurs, and from the ROM to the CPU if a cache miss occurs, but a block replacement is not executed.
