The present research is part of an effort to develop tools that make the lens design process more systematic. In typical optical design tasks, the presence of many local minima in the optical merit function landscape makes design non-trivial. With the method of Saddle Point Construction (SPC) which was developed recently ([F. Bociort and M. van...

We report on our investigation of dry cleaning of reticles with a microwave induced hydrogen plasma on dummy reticles. The dummy reticles were manufactured with 70 nm ALD grown TaN on a Ru surface and test structures were patterned with lines and spaces ranging between 250 and 400 nm. After processing the test structures were contaminated with e...

Particle free handling of EUV reticles is a major concern in industry. For reaching economically feasible yield levels, it is reported that Particle-per-Reticle-Pass (PRP) levels should be better than 0.0001 for particles larger than 18 nm. Such cleanliness levels are yet to be reported for current reticle handling systems. A reticle handler was...

Motivation - It is becoming necessary to seriously consider self-management in the treatment of chronically ill patients. A number of self-management applications have already been developed, but an explicit theoretical model is lacking. The PERISCOPE-project aims to provide (1) a conceptual framework for self-management systems aimed at...

A method for actinic inspection of EUV mask blanks is described, in which EUV photoresist is applied to the blank, flood exposed with EUV, and developed. The effect of both phase and reflectivity defects on the reticle is described in terms of a variation in intensity and phase of the standing wave in the resist. Thin film simulations are...

During the author's active time in vision research a change in attitude took place from 'visual performance' as a criterion to justify higher light levels, to 'visual ergonomics' as a more comprehensive approach to improve visual work conditions. Some personal memories of this transition period may serve as a historic framework. © 2008...

For the Wendelstein 7-X stellarator, which will allow quasicontinuous operation (τ30 min) with 10 MW of electron cyclotron radiation heating power, a conceptual design study for an IR/visible viewing system (IVVS) has been elaborated. Ten such systems, as part of the machine protection system, will be required for real time monitoring of all ten...

Objectives: To assess male lung cancer risks for industrial sectors in the Netherlands and to estimate the proportion of lung cancer attributed to working in specific industrial sectors. Methods: Associations were studied among men aged 55-69 years (n = 58 279) from the prospective Netherlands Cohort Study. 1920 incident lung cancer cases were...

We have designed a novel sub-mm radiation detector based upon a twin slot antenna placed in the focus of a Si elliptical lens. We use a novel Electromagnetic Band Gap (EBG) super-layer, consisting of 2 1/4 gamma dielectric layers of Si (ε=11.7) and SiO2 (ε=4) and a Si carrier wafer to enhance the directivity of the feed. The antenna is coupled...

The European Southern Observatory (ESO) has started technology development for their next generation optical telescope. Due to its ultra large collecting area, The European Extremely Large Telescope (E-ELT) will require a paradigm shift in telescope design to keep the overall program cost at an acceptable level. The E-ELT will feature a 42 meter...

ESO is building the Phase Referenced Imaging and Microarcsecond Astronomy (PRIMA) facility for the Very Large Telescope Interferometer (VLTI) in Chile. PRIMA will enable interferometric imaging of very faint objects and high precision astrometry with both Unit (UT) and Auxiliary (AT) telescopes. The PRIMA facility consists of four major sub...

Effects of field-of-view restrictions on the speed and accuracy of participants performing a real-world manoeuvring task through an obstacled environment were investigated. Although field-of-view restrictions are known to affect human behaviour and to degrade performance for a range of different tasks, the relationship between human manoeuvring...

For the development of an Exploding Foil Initiator for Insensitive Munitions applications the following topics are of interest: the electrical circuit, the exploding foil, the velocity of the flyer, the driver explosive, the secondary flyer and the acceptor explosive. Several parameters of the EFI have influences on the velocity of the flyer. To...

This paper proposes a novel imaging architecture suited for use in the mm and the submm wave regimes. The structure is composed by a one dimensional array of radiators in order to enhance the image acquisition time with respect to single element detection. Moreover each of the antenna elements composing the array is characterized by a relatively...

The TROPOMI instrument concept is part of the TRAQ mission proposal to ESA in response to the Call for Ideas in 2005. TRAQ (TRopospheric composition and Air Quality) has been accepted for a further pre-phase A study for the next Earth Explorer core Mission. A very similar instrument has been proposed for the CAMEO platform to the US National...
