ABSTRACT Proposal Number CTS-9700055 Principle Investigator: Lucht This is a grant for the purchase of an electron-bombarded charge-coupled device (EBCCD) digital camera system. The EBCCD is a new type of array detector which uses a back illuminated CCD (BCCD) chip as the anode of a vacuum photodiode. The gain process is much less noisy than the gain process in multi-channel plates (MCPs), the basis of the gain process for nearly all intensified CC cameras at present. The EBCCD offers numerous advantages compared to MCP-intensified CCDS, including better signal-to-noise ratio (SNR), greater dynamic range, and much better image quality. The EBCCD also has better sensitivity at low light levels. An important feature for combustion applications is that the EBCCD can be gated by turning the voltage between the photocathode and anode on and off with minimum gate widths down to at least 100 nsec. Thus the EBCCD can be used for laser imaging measurements in flames, whereas the unintensified BCCD cannot be used for such measurements because of background flame luminosity.

摘要 提案编号 CTS-9700055 负责人：Lucht 这是一笔用于购买电子轰击电荷耦合器件 (EBCCD) 数码相机系统的赠款。 EBCCD是一种新型阵列探测器，它使用背照式CCD（BCCD）芯片作为真空光电二极管的阳极。 该增益过程比多通道板 (MCP) 中的增益过程噪音小得多，多通道板 (MCP) 是目前几乎所有增强型 CC 相机增益过程的基础。 与 MCP 增强型 CCDS 相比，EBCCD 具有许多优势，包括更好的信噪比 (SNR)、更大的动态范围和更好的图像质量。 EBCCD 在低光照水平下也具有更好的灵敏度。 燃烧应用的一个重要特征是，EBCCD 可以通过打开和关闭光电阴极和阳极之间的电压来进行选通，最小选通宽度至少为 100 纳秒。 因此，EBCCD 可用于火焰中的激光成像测量，而未增强的 BCCD 由于背景火焰光度而不能用于此类测量。
