- Check water level and temperature of Haskris chiller. Ensure filter is clean.
- Before running the Bruker D4, initialize the sample changer from XRD Commander Program or if from a complete shutdown initialize sample changer first using D4 tools, then initialize using Commander, then run 'tube conditioning program in D4 Tools. (Instructions are in the XRD Bruker Manual).
- Run QAQC Standard in Bruker D4 as detailed in manual.
- Coordinate a work area in the fume hood with the chem tech and make sure there is a 10% Nitric bath available for cleaning quartz and platinum crucibles.
- Familiarize yourself with the expedition prospectus and ascertain a likely number of ICP, XRD, and pXRF samples that can be processed. Discuss sampling with Curator and applicable scientists. The core lab is your primary duty and x-ray must come secondary to that unless arrangements are made with the Lab Officer to meet specific objectives. Scientists should be made aware of this and that it is not reasonable to expect high resolution on a high recovery expedition.
- Provide training to scientists on using XRD software (EVA and Highscore)
- Provide training to scientists on hand held XRF in instrument operation, sample preparation, and data upload/download procedure
- Provide XRF safety training /wiki/spaces/LN/pages/7338164927 to scientists who uses hand held XRF. Check out and assign dosimeter ring to individual scientist. Ensure they understand all safety concern and sign required document.

- Maintain AMS inventory sheet. Do physical counts of supplies.
- If the equipment is not operating properly, learn how to fix it. Only qualified technicians should attempt to make more than minor adjustments or repairs to the instruments. The Xray technician should attend the Bruker, Olympus and Aeris courses if available on shore to become qualified at identifying problems and trouble shooting. Communicate with vendor technicians (Bruker, Olympus Aeris) and E.T's if assistance is required.
- Monitor oil levels in vacuum pumps. Change oil regularly, and perform one full service and maintenance of pumps per expedition.
- Monitor water level in Haskris water pump. Clean or change water filter as necessary.
- Ensure desiccant in desiccators is dry and ready for use. Oven dry if necessary.
- Clean freeze-drier valves, vials, and the desiccators. Replace filters as required. Drain water from the unit and dry inside. This is performed as needed (~ once a week).
- Record and date any maintenance in the XRD maintenance log on confluence. For all correspondence with vendors, ALO and LO's concerning maintenance and repairs, CC your cross shift.
...
- Write the end-of-Expedition tech report, follow the outline of the previous report, give a copy to the Lab Officer.
- Make sure all data are sent to LIMS before the MCSs cut off database access. All non-essential data should be erased from the hard disks of all the computers.
- Work with the Curator and scientists to determine where residue powders will be sent.
- Pack up equipment being returned for repairs and give the Assistant Lab Officer the following information: IODP inventory number, value, weight, serial number, model number, vendor's name and country of manufacture.
- Give the Lab Officer a list for port purchases if any.
- Clean the lab and assigned area following the cleaning instruction listed by the LO/ALO. Bring all the trash to the incinerator. Glass and sharps get disposed of in port call.
