Connecting to Triton by Oxford Instruments in Python

Instrument Card

The Triton family of cryogen free dilution refrigerators has led the way in ultra-low temperature experiment-readiness with its leading-edge superconducting magnet integration, sample loading mechanisms and sample wiring options. With over 300 systems installed worldwide, Triton is used in worldleading science across quantum technology, spintronics, optics and many other cutting-edge applications of condensed matter physics.

PROTOCOLS > SCPI

📄 IDN

Query a device's identity through the universal *IDN? SCPI command.

📄 MEASURE VOLTAGE

Query an instrument's measured output voltage, such as a DMM or power supply.

📄 SCPI WRITE

Write a SCPI command to a connected bench-top instrument and return the result.

QCodes

import qcodes as qc
from qcodes.instrument_drivers.oxford.triton import Triton

# Connect to the Triton Dilution Refrigerator
triton = Triton("triton", "TCPIP0::192.168.1.100::5000::SOCKET")

# Initialize the instrument
triton.init()

# Set the temperature of the mixing chamber to 100 mK
triton.mixing_chamber.temperature(0.1)

# Close the connection to the Triton Dilution Refrigerator
triton.close()

In this example, we import the necessary modules and classes from Qcodes. We then create an instance of the Triton class, passing the IP address and port number of the Triton Dilution Refrigerator as arguments.

Next, we initialize the instrument using the init() method. This step is important to establish communication with the instrument and ensure that it is ready for use.

We can then use various methods provided by the Triton class to control the instrument. In this example, we set the temperature of the mixing chamber to 100 mK using the temperature() method of the mixing_chamber attribute.

Finally, we close the connection to the Triton Dilution Refrigerator using the close() method.

Note that you may need to modify the IP address and port number in the Triton constructor to match the actual address and port of your Triton Dilution Refrigerator.
