Light Flash Apparatus (LFA)

38000000 Laboratory, optical and precision equipments (excl. glasses)

Supplies

Aarhus University intends to buy a Light Flash Apparatus (LFA) for research. The LFA will be used for measurement of thermal diffusivity and conductivity of various scientific samples at elevated temperatures. The samples are of limited size, typically discs or squares with a size of 10 or 12.7 mm. Of special importance are very thin samples of single crystals. For these samples we expect a half time for the temperature rise after applying the light pulse of 10-50 microseconds and in some cases even less. We thus require an apparatus able to supply short light pulses of no more than 10 microseconds.

Aarhus University intents to buy a Light Flash Apparatus (LFA) for measurement of thermal diffusivity and thermal conductivity for research purposes. The LFA will be used within a broad range of research topics within materials science, including energy materials, structural materials, materials with various novel electronic properties, etc.

Our research samples assume a broad range of shapes and sized, but all of them are small. Another common feature is that they consist of heavy elements, which results in a relatively low heat capacity, thermal conductivity, and thermal diffusivity. The largest samples are round discs with a diameter of 12.7 mm (½ inch) and a thickness of 1-2 mm. For this range of samples a pulse energy of less than 10 J is required and a pulse duration of several milliseconds is acceptable.

The smallest samples consists of thin sheets of single crystals. These can typically be cut into 5 or 10 mm squares with a thickness of around 10 μm. While the heat capacity, diffusivity, and thermal conductivity of these samples are also low, the very limited size results in very low required pulse energy and a very short maximum pulse duration. Based on the expected physical properties of these samples, pulse durations down to 10 μs are required with pulse energies up to 10 mJ or slightly less.

The materials are of interest for application between room temperature and 1200^oC and we hence require a LFA with a furnace capable of reaching temperatures of at least 1200^oC. An important topic for us is the thermal stability and degradation rate of physical properties at or above the materials respective operating temperatures. This degradation usually has a characteristic time scale of 2-4 hrs at the temperatures of interest and we thus require a fast furnace to be able to reach and stabilize these temperatures before significant degradation has occurred.

We thus have the following requirements for the LFA:

1) The LFA must be able to directly measure the thermal diffusivity and infer the heat capacity and thermal conductivity via comparison to a standard material.

2) The LFA must support measurement under both vacuum and inert gas, such as argon, with both a static pressure and dynamic gas flow.

3) Industry standard accuracy and repeatability for thermal diffusivity and heat capacity. Accuracy and repeatability of no more than: Diffusivity: 3 %, heat capacity: 5 %.

4) Tunable pulse duration and energy. The minimum pulse duration must be no more than 10 μs. The pulse energy must be on the order of 10 mJ in the 10-20 μs pulse range and up to 10 J with at most 5 ms pulse duration. The energy must be tunable below these values for all pulse durations.

5) The LFA must be equipped with a furnace with precise temperature control between room temperature and 1200^oC.

6) The furnace must be fast and able to reach and stabilize 1000^oC, starting at room temperature, within 45 minutes or less.

7) The LFA must have long operational times between refilling liquid nitrogen, either via a tank with sufficient capacity for at least 24 hrs of operation or include an automatic refill system.

8) The LFA must be able to measure at least three samples simultaneously, e.g. a reference and at least 2 samples for comparative degradation studies.

9) The LFA must include sample holders for round discs of 12.7 mm diameter and 10 mm squares as well as appropriate standards for these sizes.

Please contact Aarhus University, if you have a comment about this notice - udbud@au.dk

Following the notification, a standstill period of 10 calendar days will be held in accordance to paragraph 3 of Act No. 593 of 2 June 2016 on the Danish Act on the Complaints Board for public Procurement. This implies that the Contracting Authority cannot sign the Contract with the winning Tenderer before the standstill period has expired.

In case of complaints about tenders or decisions, e.g. award of contracts covered by Section II or III in the Danish Public Procurement Act must be submitted to the Complaints Board for Public Procurement (Klagenævnet for udbud) within 45 calendar days from the day after the contractor published a notice in the Official Journal on the conclusion of a contract. At the latest concurrently with submission of an appeal to the Complaints Board for Public Procurement, the complainant must inform the Contracting Authority of the alleged infringement, and whether the appeal is to be referred to the board.
