ESTABLE3mK. A collaborative project between Optical Development, Sevilla and QUCAM to build an ultra-stable Fabry-Perot reference cavity for Radial Velocity Spectroscopy. Sub milli-Kelvin stability is maintained for periods of >24hours.
Performance Overview Control System User Interface Sample data Controller Manual
The temperature controller automatically records servo data in an internal EEPROM. This data is available over the USB interface. A Python2 application is offered to visualise this data, some of which is shown below. Note that the optical table data (CH2) is obtained using a servoed sensor. It will of course therefore be insensitive to long-period drift errors in the servo loop. It is shown merely to demonstrate the low read noise of the temperature channel.
