Last hutch construction video (avi format, 9.6 MB). This includes snapshots from Nov 30 through Dec 7, 2015 and runs about 1 minutes 19 seconds. The soundtrack is a Yakety Axe, a Chet Atkins arrangement for steel guitar of Yakety Sax (which many know as the Benny Hill theme). This music is in the public domain.

Today's big event was the unpacking and assembling of the optic for the focusing mirror (M2).

The mono crystal cage was moved into position before work on M2 began.

A few hours later, Beau had the bender assembled and the optic in place. This is now ready for survey.

Today the second diagnostic module (DM2) and the focusing mirror (M2) were installed.

Today there has been some nice progress towards installation. Much of it is not very photogenic, but a lot is getting done.

In the first photo, Ian and Beau are lowering the mono off its wheels and onto its grouted plate.

The mono is back in its home. Note DM1 just upstream Travis is mostly done with cable pulling in the B hutch Cables going upstream tothe XAS table Signal and SHV cables

Diagnostic module #1

After some leak checking and driving the various actuators, it seems as though DM1 survived its tumble last week. Amazing!

Bremsstrahlung shield

The Bremsstrahlung shield stand is the next component after the monochromator. Before it was picked up from the floor after last week's delivery accident, the shielding parts were removed from the stand. What you see below is the shielding, sitting on a pellet jack, waiting from installation.

A new problem crops up. Notice below that the pink beam stop (the copper piece with the hole for the beam to pass through) is offset from the center of its flange. The flange was welded in place rotated by 180 degrees. The radiation safety bits are in the correct location, but the flange is offset in the wrong direction. This means that additional strain will be placed on the bellows connecting this to the monochromator.

The primary Bremsstrahlung shield is the thick, red-painted, lead block just below the beam pipe. The purpose of this component is to stop the high-energy gas Bremsstrahlung originating in the storage ring. Because we have an upward-deflecting mirror in the front-end, the pink synchrotron light enters the hutch above the primary Bremsstrahlung. Hence the primary Bremsstrahlung shield is below the X-ray beam path.

The copper bit is the pink beam stop. It's purpose is to stop the pink beam from t he front end mirror in the situation where the first monochromator crystal is, for some reason, removed from the beam. It is water-cooled – note the cooling line brazed into the copper and sticking out in the foreground.

The big red mass of lead is secondary Bremsstrahlung shield #2. The purpose of this is to catch Bremsstrahlung radiation which has scattered off of some component upstream, either in the A hutch or in the front end. Its large area is necessary to catch the full possible fan of such a scattering event.

Picking up the pieces

On May 11, the first diagnostic module and the Bremsstrahlung shield stand were delivered, along with several crates of smaller kit. Unfortunately, the two large crates containing those components toppled over in the back of the delivery truck. Here is a photo journal of the work of the BNL riggers extracting that mess from the back of the delivery truck.

Today, the riggers came back to pick up all the components.

The solution to having DM1 slide along the floor was very clever. The BNL riggers are awesome!

Use a second fork lift to lift from the other side Up, up, up… Getting there… Almost up, pull, Jimmy, pull! And up! Whew!

Other activities

The new mono plate allows the mono to be translated laterally between sets of Si(111) and Si(311) crystals.

I love the photo of M3. It looks like a real beamline!

Removing M2, M3, and DM2 from their pallets

M2 is our toroidal focusing mirror. M3 is a planar harmonic rejection mirror. DM2 is the diagnostic module between the mono and M2, it has a screen and slits.

Ian begins work to replace the crystal cage. The mono has been removed from the hutch to allow space to install the first diagnostic module, which will arrive in a few days.

Pump stand for the transport pipe

This stand supports a shielded box which holds an in-line ion pump. This, along with the pump on the fluorescent screen shown above, pumps out the transport line between the hutches.

The holes don't quite line up with the holes in the floor Art the rigger is waiting to lift the shielded box Ian drills out the holes on the stand's legs More drilling
sm_10.35.13.jpg sm_10.35.44.jpg sm_10.46.48.jpg sm_10.47.07.jpg

The box is then jockeyed into position on the stand. This thing weights a lot!

At this point, I had to run away to make a presentation about BMM to the Radiation Safety Committee. When I returned, the transport pipe was in place.
