Advanced Design for Neutron Scattering Instruments

I have used COMSOL Multiphysics® for more than ten years as a design tool. To share this experience, I selected the following three examples of device development for neutron scattering instruments.

In the first example, I show a climate chamber, which is used as a sample environment for small-angle neutron scattering experiments. This novel climate chamber enables us to humidify and dehydrate small sample foils (for example, fuel cell membranes) in situ, in a temperature range between 50 and 100°C. I show the calculated temperature, humidity, gas flow, and mechanical stress distribution inside the climate chamber during operation.

The second example shows a space-saving method to host a neutron polarizer in an iron-containing monochromator shielding of a time-of-flight spectrometer. In this example, you can learn how to create a robust, homogeneous, rectangular magnetic field inside an iron tube.

With the third example, I show the first part of the comprehensive description of an acoustic levitator. Acoustic levitators are used to levitate small samples (up to 6 mm) at a stable position in a gas or liquid environment. I present a practical model, which includes basic properties and interactions in a stepwise approach to the realistic world of acoustic levitators.

Thermal Management Simulations for Optimized Optoelectronic Packaging

Here, we present a thermal model of a packaged midinfrared laser with an embedded thermoelectric cooler and sealed in air. The advantage of using the COMSOL Multiphysics® software is clearly identified by the availability of the multiphysics coupling scheme for solving simultaneously thermal, electric, and fluidic models in both a stationary and time-transient fashion.

The integration of a laser device into a package poses a big challenge in terms of laser temperature stability at high operating power. Thermal simulations with COMSOL Multiphysics® are used in the design phase to optimize for the lowest operating temperature, ensuring the longest system reliability and lifetime. Effort in simulation is also put into finding the best possible position for tracking the thermocouple inside the package itself. Further emphasis is given to the compromises taken to achieve a realistic multiphysics model by including effects such as the thermoelectric effects of the Peltier cooler; air convection inside the package; and, finally, convection and radiation on the external surface of the package. A procedure to verify the model is also shortly discussed.

Coupled RF-Mechanical and RF-Thermal Simulations for the High-Luminosity LHC Crab Cavities

The High-Luminosity Large Hadron Collider (HL-LHC) is a project to upgrade the LHC by achieving instantaneous luminosities a factor of five times larger than the nominal LHC luminosity. One of the key devices of the HL-LHC project is the superconducting radiofrequency (SRF) crab cavities. The crab cavities are RF components designed in such a way that when operated at the adequate frequency, the proton bunches are tilted, maximizing their overlap at the collision points. Two crab cavity concepts have been developed: the double-quarter wave and the RF dipole.

The presence of RF fields inside the cavity volume requires the use of multiphysics numerical models capable of coupling these fields with the thermal and mechanical problems. In fact, the RF field presents a strong dependency on the cavity shape, whereas the mechanical, thermal, and electrical properties of the materials may substantially vary as a function of temperature, which is mutually dependent on the RF field.

In this talk, I will show examples in which the capabilities of the COMSOL® software have helped to improve the design of the cavities and their subcomponents in both RF-mechanical and RF-thermal problems.

Acoustic Modeling of a Minute Repeater

The aim of this project was to model and optimize the acoustics of a minute repeater on one of the high-range items made by a Swiss watchmaker. We based our work on a simplified geometry made with PTC® Creo® Parametric™. The mesh model includes the gongs, the bottom plate, a dozen fixed pieces, the case, and the glass.

The acoustic field was computed thanks to the finite element method. The comparison of the results with the tests shows a 90% correlation of the eigenmodes. A reseting of the experiments and the computations was necessary in order to validate the model. We optimized the geometry to get a proper and louder sound.

A dedicated simulation application created with the Application Builder in COMSOL Multiphysics®, deployed via COMSOL Server™, and synchronized with LiveLink™ for PTC® Creo® Parametric™ permits watchmakers to autonomously set and tune the length of the timbres. This results in a significant time savings and a gain for the homogeneity of the production.

We compared the quality of the sound produced by watchcases made of different materials, such as gold and titanium, to optimize the volume of the case made with additive manufacturing.

We used COMSOL Multiphysics® as well as the Acoustics Module, Optimization Module, COMSOL Server™, and LiveLink™ for PTC® Creo® Parametric™.
