130/302


  • Target exchange system

For the exchange of highly radioactive components a half-automated rail system is specified. A transport container with a total weight of approx. 10 t pulls the component out of its iron shielding. Connection to the component is performed by a pneumatic quick coupling system fixed at a carrying frame. The container then drives on rails under a shaft and the component is transferred through the shaft into a shielding flask. Part of this tender are a mobile operator panel, rails and parts for securing of the transport path too. Due to the radiation level this tender must be built in accordance with KTA regulation, but KTA certification is not necessary.
Expected tender will start in 2019.

178


  • Shielding flask

Purpose of the shielding flask is the transport of highly radioactive components between two buildings on site. Equipped by a carrying frame and a winch that pulls the component through a shaft of a length of about 8m. Wall thickness of the flask is designed in a way that at surface the maximum dose rate is below 100 µSv/h. Total weight is about 25 t. Part of this tender is a transfer frame too, with the same carrying frame like the shielding flask to lower down new components through the shaft. Due to the radiation level this tender must be built in accordance with KTA regulation, but KTA certification is not necessary.
Expected tender will start in 2019.

178


  • Target station

Target station is built out of low-alloy steel with a total weight of about 42 t and shall have a low cobalt content due to its radioactive exposure. On top of it the rails of the half-automated exchange system are mounted. For opening the station a sliding door is equipped, moved by a spindle drive. Inside of this shielding there is a motor driven adjustment table to fix the components properly during the experiment. Due to the radiation level this tender must be built in accordance with KTA regulation, but KTA certification is not necessary.
Expected tender will start in 2019.

178


  • Mobile heavy duty robot

For one special area this robot must be installed on a flat transport platform for heavy loads operating in tight spaces. The platform need enough space for batteries and electronic on board.
The robot must master the handling of heavy loads up to 1 t over a distances of up to 2.5 m precisely within 0.1 mm accuracy. Alignment shall be with an installed laser positioning system against the chamber. Speed is not of major importance. The robot must handle two kind of tools: a lifting hook and a gripper.
Bonuses including a camera, radiation sensor and data transport over Wi-Fi.
Expected tender will start in 2019/20.

009


  • Precision aluminum panels

Very precise manufactured aluminum panels, especially thickness must be up to a few µm over the entire surface of the desired shape. Second criteria a small but not tiny surface roughness. Expected tender quantity will be 17 pieces, some in a slight wedge shape and others just plane parallel, all with diameters ranging from 200 mm to 400 mm.
Expected tender will start in 2019/20.

216


  • Crane with drum lifter in decay basin

The radioactive decay basin as part of the hot cell has a drum storage for 20 x 200 liter barrel. The provided system must be able to take a barrel in and out through a floor opening. Further criteria are a certain movement accuracy and a fulfillment of special safety requirements. Due to the radiation level this tender must be built in accordance with KTA regulation, but KTA certification is not necessary.
Expected Tender will start in 2018/19.

318


  • Drum roller conveyor and turntable for hot cell

In a corner of the radioactive hot cell, the barrels are filled with contaminated material. Afterwards the barrel must be moved in standing position on a 3.5 m long roller conveyor to the next room. At end a turntable is integrated in the roller conveyor which will turn the barrel while at the same time a detector measures the dose. The detector itself is not part of the tender. Engines will be positioned in the decay cell; therefore occasionally manual maintenance is possible. Due to the radiation level this tender must be built in accordance with KTA regulation, but KTA certification is not necessary.
Expected tender will start in 2018/19.

318


  • Maintenance-free turntable in hot cell

Components up to 7.5 t will be placed 3 m above ground on a turntable with a diameter of 2 m. With adjustable holders, the system fits for different sizes and is accessible from all sides with manipulators. The turntable rests on four legs with free space to work in between. These feet are anchoring in steel sleeves in the ground. The front is accessible with master-slave manipulators, the rest only with a heavy-duty manipulator. An engine is preferable, but a big crank may work too.
Since maintenance is problematic in this radioactive hot cell, the system shall operate for 10 years without maintenance, besides occasionally oiling. Due to the radiation level this tender must be built in accordance with KTA regulation, but KTA certification is not necessary.
Expected tender will start in 2018/19.

318


  • Clean room for a laser lab

For our laser systems, a safe, closed, and clean room (up to 50 m^2) must be built. Low levels for dust particle concentration are important to prevent contamination of lasers, optics, and detectors. Flow boxes are needed. Temperature and humidity control are required to provide stable conditions for the lasers. The material of the walls and the roof of the room must be modular, light weight, and have enough thermal and acoustic insulation.
Expected Tender will be in 2018/19. 

250


  • Vacuum for beam line

A high vacuum (up to 1*10-7 mbar) beamline, based on CF-flanges and good quality stainless steel, is required to transport a laser beam from the lab to the accelerator. The total length is about 25 m. We prefer the use of standard CF-components. Also a special construction is required to support the beam line. Since it must be mounted high up, we prefer a construction in which the beamline is supported (is hanging) from the ceiling.
Expected Tender will be in 2018/19.
