Description

Posted: Dec. 10, 2024, 1:05 p.m. EST

The LAP program seeks to develop large-area photocathodes. Photocathodes can be found in devices such as photomultiplier tubes, image intensifiers, high-power electronics, and even free electron lasers. Photocathodes typically use low-work function metals or semiconductors and are applied in sub-micron thicknesses on planar surfaces with millimeter to centimeter-scale areas.
Photocathode performance can be characterized by attributes such as quantum efficiency (QE), lifetime, and mean transverse energy (MTE). Metals such as copper and magnesium have low QE but are well-understood, robust, and easy to obtain. CsTe is a leading semiconductor used within the accelerator community with a reasonable balance of QE, lifetime, and MTE. Diamond has been examined for switching applications but may hold promise as a photocathode. Other materials, such as the alkali antimonides, could offer high QE operation at longer wavelengths but may have lifetime, process, and handling challenges. In addition, recent work has also focused on increasing QE and lowering emittance through patterning techniques. ,
LAP seeks manufacturable photocathode material systems with high quantum efficiency that can be produced in large areas with substantial lifetimes and manageable handling requirements. LAP will develop and produce photocathodes that will be incorporated by the government team into a prototype system.

Background
The Large-area Photocathodes (LAP) program is initiated to develop photocathodes that are essential components in devices such as photomultiplier tubes, image intensifiers, high-power electronics, and free electron lasers.

The program aims to produce manufacturable photocathode material systems with high quantum efficiency that can be produced in large areas while ensuring substantial lifetimes and manageable handling requirements. The government team will incorporate these photocathodes into a prototype system.

Work Details
The contractor is expected to provide a comprehensive technical approach that includes:
1. A description of the overall proposed solution, including anticipated capability and innovative claims.
2. A detailed description of innovative claims related to the photocathode material, manufacturing process, and expected performance metrics. This includes strategies for self-evaluation of sample photocathode prototype performance and supporting overall prototype development, along with manufacturing feasibility.
3. Identification of technical and security risks along with mitigation strategies.
4. A credible program development timeline that supports required schedules and milestones. Additionally, a price breakdown must be provided across major milestone events, identifying any risks that may lead to increased costs. Teaming/subcontractor roles must be identified, including their qualifications and contributions to the technical approach. Data rights regarding proposed solutions must also be clearly defined.

Period of Performance
The period of performance will span multiple months or years as defined by the project milestones and development timeline.

Place of Performance
The geographic location(s) for contract performance have not been specified.
