In recent years, silicon photonic platforms have undergone rapid maturation enabling not only optical communication but complex scientific experiments ranging from sensors applications to fundamental physics investigations. There is considerable interest in deploying photonics-based communication and science instruments in harsh environments such as outer space, where radiation damage is a significant concern. In this study, we have examined the impact of cobalt-60 γ-ray radiation up to 1 megagray (MGy) absorbed dose on silicon photonic devices. We do not find any systematic impact of radiation on passivated devices, indicating the durability of passivated silicon devices under harsh conditions.

Introduction: The dose calculation plays a crucial role in many aspects of contemporary clinical radiotherapy treatment planning process. It therefore goes without saying that the accuracy of the dose calculation is of very high importance. The gold standard for absorbed dose calculation is the Monte-Carlo algorithm. Methods: This first of two papers gives an overview of the main openly available and supported codes that have been widely used for radiotherapy simulations. Results: The paper aims to provide an overview of Monte-Carlo in the field of radiotherapy and point the reader in the right direction of work that could help them get started or develop their existing understanding and use of Monte-Carlo algorithms in their practice. Conclusions: It also serves as a useful companion to a curated collection of papers on Monte-Carlo that have been published in this journal.

“…One of the additional PMMA slabs of the phantom was modified to fit four alanine pellets placed with center in the corners of a 1 cm × 1 cm square in a 2.5 cm diameter circular ABS holder (see Figure 2 Cobalt-60 reference irradiations are carried out in a Gammacell -a shielded enclosure, with a number of cylindrical cobalt-60 source pencils arranged around the sample at an approximate radial distance of 10 cm and which have an approximate height of 20 cm. The irradiator is very similar to the Nordion GC-220 in design (Hefne, 2000;Rodrigues et al, 2009). The standard ABS holder containing four alanine pellets is placed inside polyether ether ketone (PEEK, C 19 H 12 O 3 ) cylinders inside an aluminium can which is able to have its temperature controlled, which is all placed at the sample position.…”
