Up to now the ramming for the eastward trench has been completed and the first 100 m for the northward trench have been done.

Except for the first week of January work has completely been stopped. The wheather is extremely cold right now, the ground is frozen to a depth of about one and half a meter. This morning's (9.2.1996) temperature has been -17°C. Within the next week there is no change to be expected.
Now, in the middle of May 1996 the ramming of the second trench is done, except for the last 150 m. The I-beams and transverse reinforcement beams are welded at the first 400 m. The northward trench is dug out at a length of about 500 m and will be finished within the next week. The first two sections of the rail where the tube will be hung at and pushed out of the end house have been installed and works all right. We have set up a wooden 'hut' in front of the eastern end-house for storing up to six tube sections before welding them together inside the end-house. Inside the eastern end-house the 'platforms' are set up and the major part of the electrical installation ist done.
We intend to begin tube installation around end of May. A short tube section has been taken out of the actual manufacturing process and its vacuum properties (outgasing rate, residual partial pressures before and after baking) are checked.
Now, on the 24th of June, the eastern end-house is finished, the welding machine is in place, and the rail where the tube will be hung from is installed and adjusted. We have built a "wooden hut" with a shelf inside which takes up to 6 pieces of the 4.5 m tube sections for short term storing capacity. The trench is ready and covered with corrugated sheet metal. The welding of the tube will (hopefully) begin within a week or two.
The ramming of the second trench is nearly completed. There are only about 100 m left. We are currently checking the vacuum properties of a 75 cm test section taken out of the manufacturing process. The first results look promising.

Fall 1996: Progress Report
November 14, 1996
For the moment just a short note in order to report on the progress made since June. New pictures will follow as soon as our new scanner has been installed.
All the houses are finished, but still empty. Next, cranes will be installed. Then cleaning and painting can be done followed by the floor covering. Large containers have been placed in front of the houses, serving as entrance area and clean room gate.
Telephones have been installed. Feel free to call: +49-511-762-6165 (Central house) or +49-511-762-6148 (Eastern end house).
The trenches are all covered by corrugated iron roofs shining in the sun. (Should give an interesting look as seen from the sky!) The welding of the first tube makes good progress - 420 m have been completed. We hope to see it finished by the end of the year. (Yes, we are professional optimists.)

Our new scanner has been installed. The first new pictures can be seen at the September and October pages. For the moment the main pictures are rather large (cf. the Oct. pics ~ 350k).
The welding of the first tube continues to make good progress – 430 m have been completed. We still hope to see it finished by the end of the year.

The welding of the first tube has been finished!
Merry Xmas & a happy New Year to all the people of GEO600!
