Guest: Martin Castillo Host: Markus Voelter Shownoter: Alexander Grote
During our tour NorthWest 2017 I visited the drop tower at Uni Bremen’s ZARM and talked with Martin Castillo, the head of material science at the facility. We discussed the basics of microgravity research, the technical aspects of the tower, how to set up experiments, and also about his particular work in material science.

Great episode!
This video doesn’t go into anywhere near the detail that OmegaTau does, but I found it useful for visualising things. It shows a catapult ‘flight’.
And yes, I forgot the link…

Thanks, Markus – Very informative!
There was a comment something like “I’ve never heard of infra-red being used for data transmission”.
The internet backbone and high-speed transmission within data centers use infra red light, carried through optical fibers. This large industry has produced a series of economical infra-red laser modules capable of transmitting at speeds of 10Gbps and higher, over distances of 500m to 70km.
These modules could be adapted to transmitting 100m through a vacuum, provided you avoided excessive reflections off the walls of the tube (which would create multi-path transmission). The more recent laser modules are even designed to detect and cancel multi-path reflections.
Yes, great video, watched it for preparing the episode as well. Thanks :-)
Right. Of course I know about light-based information transformation in fibers. But I wasn’t aware of the wireless kind.
Von den Abmessungen her ist der ZARM Fallturm vergleichbar mit der Röntgentestanlage Panter, http://www.mpe.mpg.de/heg/panter_de. Aber ein Turm ist natürlich viel cooler als ein liegendes Rohr.
Thank you.
