  \\Adjust the nozzle position by eye until it nearly touches the tape and roughly meets the X-ray interaction point. Then, move to the control hutch to use the on-axis microscope for fine adjustment. Move the nozzle tip to the beam position (red X) and write down the absolut nozzle position. From there move the nozzle in +x to your desired distance.Different distances combined with the tape speed result in several delay times for time-resolved experiments.
