Abstract:
Disclosed is a circuit for controlling the temperature and the bias voltage of a detector used by an X-ray analytical instrument. The circuit uses a single common reference voltage for the temperature measurement and for all the ADCs and DACs in the circuit, resulting in reduced drift and improved reproducibility of detector temperature and bias voltage. ADCs with a larger number of bits are used to produce precision values of the temperature, the bias voltage, and their respective setpoints. The setpoints are digitally varied until the precision setpoint values correspond to desired values of temperature and bias setpoints.

Claim (Index 1):
A circuitry for controlling a cooling power supply providing cooling power to a cooling unit of a detector of an X-ray analyzer, the circuitry comprises:\n a thermal measurement element producing a temperature measurement of the detector and subsequently a temperature voltage, a controlling circuit providing a control signal for controlling the cooling power, the controlling circuit further comprises:\n a single common reference element providing a common reference voltage, \n a digital-to-analog converter (DAC) configured to produce a setpoint voltage based on a pre-determined setpoint temperature value, \n an analog-to-digital converter (ADC) configured to digitize the temperature voltage and the setpoint voltage and produce a precision setpoint value, wherein the precision setpoint value is used to produce an adjusted setpoint voltage, \n a comparator producing a differential value between the temperature voltage and the adjusted setpoint voltage wherein the differential value is used as a basis for the control signal, wherein the common reference voltage is referenced by the thermal measurement, the DAC and the ADC.
