Within the Flexnode Plus project the long-term degradation characteristics of a proton exchange membrane (PEM) electrolyzer (5.5 kW, AC, 1 Nm3/h H2) and fuel cell (1.0 kW, DC, 0.9 Nm3/h) was experimentally tested. The electrolyzer unit was operated at various loads and pressures for approximately 750 …

The aim of this report is to document the configuration, design and testing of an innovative hybrid electric weed brush to be carried by a Antonio Carraro SP5008 Hydrostaticly articulated multi-purpose maintenance tractor. This project is issued by Hissink Custom Made Machinery, as an graduate assingment …

SRON is the Dutch national expertise institute for scientific space research and is part of NWO. It plays an important role in delivering contributions to the national and international space-research communities. Currently one of SRON’s involvements is in the X-IFU instrument for the Athena space X-ray …

Multiple scientific and industrial applications such as telecommunication and quantum cryptography causing a rise in the development of the superconducting nanowire single photons detectors (SNSPD). In the last decade, the characteristics of the detectors improved but run against the problem that the …

Cruise ship fires are not uncommon. Fire on board of the cruise ships is one of the most dangerous accident that can occur at any moment. The damage caused by fire is huge and can negatively affect the company’s reputation. There is a product on the market that can, according to the manufacturers, detect …

The Dutch Transmission System Operator (TSO) TenneT TSO B.V. is planning to build a 2 km to 4 km long 150 kV superconducting cable connection in the Dutch high voltage grid. Superconducting cable systems allow for connections with no external magnetic field which is beneficial due to society's concerns …

The aim for this thesis is to set up and develop electroplating technique for depositing gold layers. This gold layer will be used as an thermalisation layer in a cryogenically cooled X-ray detector. Key material parameter for the gold layer is a low thermal resistivity at cryogenic temperatures. Since …

A Quad Focus GridPix Gaseous Tracking Detector is under construction, to allow calibration and test beam measurements to validate the working principles of the (quad) GridPix detectors while using a focused electric field. The development is well on its way: both measurements should be able to be conducted …

Objectives: Children have a greater risk from radiation, per unit dose, due to increased radiosensitivity and longer life expectancies. It is of paramount importance to reduce the radiation dose received by children. This research concerns chest CT examinations on paediatric patients. The purpose of …
