首要项目"意大利科学和技术用于升级ALMA天文台-iALMA"的目标是加强意大利科学、技术和工业对阿塔卡马大型毫米/亚毫米阵列的贡献，该阵列是研究微波宇宙的最大的国际地面基础设施。在阿尔马内部的科学工作组（SWG）的主要目标之一，即工作包1，是为阿尔马波段2或波段2 + 3接收机的科学案例开发意大利的贡献。阿尔马频带2接收器的范围从~67 GHz（以臭氧线的不透明线复合体为界）到90 GHz，与阿尔马频带3的低频端重叠。自阿尔马频带的最初定义以来，接收机技术已经发展。现在可以在单个接收器盒中生产能够覆盖从67GHz到116GHz的整个频率范围的单个接收器，包括频带2和频带3，即所谓的频带2 + 3系统。此外，预计将对阿尔马系统进行升级，使带宽增加一倍，达到16千兆赫。因此，下文讨论的科学驱动因素也讨论了这两项改进措施相对于最初设想的第二等级制度的优势。
The Premiale Project "Science and Technology in Italy for the upgraded ALMA Observatory - iALMA" has the goal of strengthening the scientific, technological and industrial Italian contribution to the Atacama Large Millimeter/submillimeter Array (ALMA), the largest ground based international infrastructure for the study of the Universe in the microwave. One of the main objectives of the Science Working Group (SWG) inside iALMA, the Work Package 1, is to develop the Italian contribution to the Science Case for the ALMA Band 2 or Band 2+3 receiver. ALMA Band 2 receiver spans from ~67 GHz (bounded by an opaque line complex of ozone lines) up to 90 GHz which overlaps with the lower frequency end of ALMA Band 3. Receiver technology has advanced since the original definition of the ALMA frequency bands. It is now feasible to produce a single receiver which could cover the whole frequency range from 67 GHz to 116 GHz, encompassing Band 2 and Band 3 in a single receiver cartridge, a so called Band 2+3 system. In addition, upgrades of the ALMA system are now foreseen that should double the bandwidth to 16 GHz. The science drivers discussed below therefore also discuss the advantages of these two enhancements over the originally foreseen Band 2 system.
