    1) Is it possible to improve the mechanical properties of 3D-printed cellulose? (additives, fibers…)?


    Within HV applications, cellulose based insulation is still the main component for a large number of products. For future applications, mechanical strength and stability of are paramount and the present 3D-printable solutions do not seem to live up the required strength/stiffness levels.

    2) Is there a method to combine AM of soft magnetic materials with deposition of thin layers of insulating material?


    Additive manufacturing (AM) offers large opportunities to produce novel topologies of electrical motors. This is of special interest to develop high efficiency motors for electrical vehicles. It has previously been shown that good material properties of soft magnetic steel can be attained by using AM, laser powder based fusion. However, one major challenge remains. In typical electrical motors one of the largest source of losses is due to eddy currents. In traditional electrical motors laminated sheets of steel is used where the insulating lamination drastically reduce the eddy currents. Up to now it has not been possible to combine the AM process of the magnetic steel with subsequent deposition of insulating layers. Among other things, the insulating layers need to withstand the deposition of the next layer of the steel and also the interfaces need to be mechanically strong. Optimally, it should be possible to place the insulating layers totally free in the design space and not be limited to planar sections in the growth direction.

    3) What is the most suitable (low/moderate temperature) metallic bonding technique to replace a solder process?


    To phase out lead from ABB products it is of uttermost importance to find proper alternative processes. Some important perspectives are temperature, processing time, complexity, uniformity of interface, stability of interface. The selected reference system to be discussed is SnPb.

    Chemical analysis of low-level radio activated materials – what options are available?


    It’s sometimes of interest to investigate samples form cyclotron related materials from a chemical composition point of view. This can be accumulated dirt, deposits or other substances that are of interest to investigate. However often these substances are slightly radio activated and this creates problems since this is often considered a big concern/risk within companies offering chemical analysis services. Often this comes from lack of correctly understanding the risks and applying an unnecessary strict approach. What possibilities are there available to get slightly radio activated material analyzed? The attached document "A background to GEMS PET Systems AB" gives a good background to who we are and cyclotrons for PET.

    simple cleaning method for vacuum details


    The cyclotron accelerator includes a vacuum chamber where a lot of parts are included/mounted. To reduce pump down times and enable a good final vacuum level, these parts must be reasonably clean. A simple but at the same time robust/effective and environmentally friendly method is what we look for. The different materials used in the vacuum tank to some extent limits the use of detergents and methods possible. Today a combination of “YES” washing up liquid, ultrasonic (50 deg. C), deionized water rinsing and Isopropanol rinsing is used. This is followed by a 4h 100 deg. C oven drying. Final vacuum in the cyclotron is in the order of low 10 exp. -7 mbar or high 10 exp. -8 mbar.
