At the end of the period when the experiment is run, lab leaders should:

• Liaise with Lead Technicians, and send the marks to the overall Coordinator of Laboratory Experiments in Part IA or IB, as appropriate.
• Update the handover notes for the experiment, noting any weaknesses of the experiment or handout while things are fresh in your mind, and suggesting improvements to make before the experiment is run again. 
• Check the hours claimed and sign completed payment forms for unestablished staff who have worked as demonstrators.  You may delegate this task to a senior technician.
