3 TECHNICAL DESCRIPTIONThe Pneumatic Filter Shutter is an in-line device which will attenuate an x-ray beam upon theinsertion of up to four filter foils. The filter foils are held between two plates on their own carrierwhich can be remotely moved in and out of beam by pneumatic cylinders, controlled by electricallyactuated solenoid valves.

1 or two shutter blades can be attached to the foil carriers in order to control the size of the beam inthe vertical direction or to block the beam. This can be used to minimise damage to radiationsensitive samples.

The filter foil size used should be 25 mm x 25 mm square and up to 3mm thick.

4 INSTALLATION

Foil Installation4.1

CAUTION

Extreme care should be made to handle the foil carefully and with slowmovements. Failure to do so could cause the foil to tear.

Installation of the foil should be carried out in a clean environment.

When handling the foil use clean gloves.

The air supply should be disconnected.

To remove a foil, follow the steps in reverse.

Steps

1. Place the Pneumatic Filter Shutter on a clean surface with the solenoid mounting plate facingupwards.

2. Unscrew the 4xM5 Cap head screws on the lower housing.

3. Remove the lower housing to expose the foil holders (Figure 2).

User Manual

4. Wearing clean, lint-free, gloves and using a clean screw driver loosen the filter holder nut onthe chosen filter holder assembly so that it comes free from the pneumatic cylinder (Figure3).

5. Unscrew the 4 x M2 Cap head screws and remove the foil securing plate (Figure 3).

Figure 3: Exploded view of foil holder assembly

6. In a clean, draft free laboratory gently remove the foil from its container. It is essential that therebe no excessive air movement. Gripping the edge of the foil (within 2 mm) with small wafertweezers is a recommended way of handling the foil. Always move a foil such that it travelsedgeways to the air, as even the slightest draft (such as a breath) against the face of the foilmay break it.

7. Carefully place the foil into the foil holder. Ensure that it is the right way around.

8. Reattach the securing plate and the filter holder assembly to the pneumatic cylinder.

9. Close the Pneumatic Filter Shutter and tighten the screws. Note: The Pneumatic Filter Shutteronly closes one way.

5 PNEUMATIC FILTER SHUTTER BEAMLINEINSTALLATION

CAUTION

When attaching the Pneumatic Filter Shutter to the beamline be aware thatshock vibration could cause the foil to tear.

The air supply for the Pneumatic Filter Shutter needs to be at 3 bar and supplied via 4 mm tube; seeFigure 4 for reference.

Figure 6: Pneumatic Installation

The solenoid valves need to be connected to a 24 V DC power supply.

The air supply needs to be regulated at 3 bar and supplied via the 4mm hose shown in Figure 6. Itshould be filtered but can be lubricated or non-lubricated.

6 OPERATIONThe foils have two positions; in and out of beam. To extend a foil in to the beam open theassociated solenoid valve. The rest position of the foils is out of beam.

CAUTION

Always raise the foil to the out of beam position before the unit is evacuatedor vented to atmosphere. Failure to protect the foil during these operationsmay result in damage.

Modes of Operation6.1

A combination of up to four foils and up to two shutter blades can be used on the four foil holders togain different attenuations of the x-ray.

7 MAINTENANCE INSTRUCTIONSBefore maintenance commences on this equipment it is important that you familiarise yourself withthe health and safety documentation provided in Appendix 1. Additionally, ensure you are aware ofand understand the specific health and safety guidelines provided by the facility you are working at.

CAUTIONS

1. When performing maintenance or other procedures, ensure that nothingcontaminates or damages the surfaces of the foils. Dirt or other particleson the surface of the foil can cause deterioration in the performance ofthe Pneumatic Filter Shutter. If the foil surfaces do become contaminatedor damaged, contact FMB Oxford for further advice. Do not attempt toremove the contamination.

2. Avoid contamination of vacuum surfaces. Make sure normal vacuumcomponent handling procedures are observed.

3. Only open and handle the Pneumatic Filter Shutter in a clean area.

4. Use clean, lint-free, gloves if any vacuum surfaces have to be handled.

5. Use only clean tools in contact with vacuum surfaces.

6. Minimise exposure to atmospheric air, as water will adsorb on exposedsurfaces and extend pumping times. Store vacuum equipment undervacuum or dry nitrogen.
